SECTION 3
APPLICATION NOTES AND
SPECIFICATIONS
3.1. System Description
The Wireless Temperature Monitoring System (WTMS) monitors temperatures of the surfaces of energized electrical equipment (see Section 6, Ref
[1], Product Specifications 16090-10).
The system consists of three components:
•
•
•
Sensors (wireless transmitters)
Receivers (signal receiving units)
Software (processing, alarming and reporting software)
Square D High Temperature Sensors are designed to actively measure the
temperature of the strategically important points on metal or insulating surfaces of current carrying parts. The Sensor design allows measuring the temperature in wide range, from 0 to 150o C. The Receiver receives the RF
signals from the Sensors with temperature, time stamp and identification information from the Sensors and relays this information to PC.
Software processes the sensor information and records it into a textual log
file. Two versions of software are available: one providing the system working
in standalone mode (TempAssure), another in conjunction with power monitoring system. A version of the Receiver is also available for integration into
SCADA and BMS systems.
3.2. How WTMS Works
WTMS is quickly and easily installed in any facility by deploying multiple Sensors in positions throughout energized equipment to continuously monitor
surface temperature. The Sensors transmit a packet every twelve minutes,
or, if the temperature is increasing fast, every six minutes.
The packet is picked up by a near Receiver/Receiver. Receivers have a typical indoor range of 100 feet with sensors mounted in equipment. The Receiver (antenna) is centrally installed in the control room (a single Receiver
can receive information from 100 sensors). However, it is recommended to
utilize at least 2 Receivers for a given area to maximize reception of the RF
signals from the Sensors.
Depending on number of the Sensors in the system and the size of facility, a
series of the Receivers can be connected in daisy chain. Once the data is
picked up by the Receiver the data is placed on the Receiver network. The
Receiver network uses standard category 5 Ethernet Cable to daisy chain
the Receivers supplying power and a way to communicate back to the PC.
Another option is to transfer the data to PC via multiple ethernet ports.
A PC installed at the facility or the existing facility network is used. In standalone mode of WTMS the TempAssure Software is installed on local PC and
sensing parameters are set (WTMS allows adjusting alert conditions to Customer specific needs). Temperature information may be reviewed by the Customer or by Square D Engineering Support (see Section 6, Ref [2], Product
Specifications 16090-11- WTMS Consulting Services) via modem or Internet.
Alerts or reports can be sent to the customer in numerous ways such as by
cell phone, two-way pager, or email. Web monitoring is also an option.

3.3. System Features
Easy Installation - Installation of software and Receiver is simple. Affix the
receiver to conduit or strut and provide power. The software is also easy to
install.
Monitoring - Software allows monitoring of the temperature readings from
all active Sensors.
Range - Antenna receives Sensor signals up to 100 feet (30 meters) away
(tested successfully up to 1000 ft.).
Population - The system can monitor an unlimited number of Sensors without interfering with one another or loss of identification.
Supervision - Sensors transmit a signal every 6-12 minutes depending of
thermal condition, so you can respond quickly to any problems.
3.4. Square D High Temp Sensors Features
The Sensors are all-in-one temperature sensors and identification tags (Fig
1). The Sensors detect ambient temperature and continuously send radio frequency information to the Receiver. The device transmits the information it
has collected using a low power RF transmission. The Sensors are calibrated
accordingly to application to give accurate temperature readings. Re-calibration is not required.
Figure 1:
Wireless Square D High Temperature Sensor
Low Cost Installation - The Sensors are wireless and can be placed almost
anywhere by using a high temperature adhesive.
Operation - In direct contact with the surface.
Long Battery Life - Sensors utilize a High Temperature 3V lithium battery
that lasts up to 5 years.

Application Notes and Installation Manual
03/2011
3.4.1 Application Sensors
Wireless sensors can be applied to any type of new or used LV and MV electrical equipment such as switchgear, circuit breakers, capacitor banks, transformers, motors, busways and cables. The Sensors can be also used on HV
and EHV electrical equipment.
The Sensors can be applied for measuring temperature of any strategically
important points inside energized apparatus, such as stationary contacts, finger clusters, stabs, bolted connections, as well as any other important locations where temperature should be controlled. The number of points to
monitor inside the unit is not limited. It is considered important to install the
Sensors on each phase of the apparatus both on load and line side. Sometimes it is possible to detect a problem based on lesser number of the Sensors, for example only on load side, but this decision should be made based
on design and application features. The only limitation is applying the Sensors would be the dimension of the space available at the point of interest,
which should be not less than 1.5 x 1.5 x 1.5 inch3 (4 x 4 x 4 cm3). The Sensors can be attached to either metallic or insulating surfaces and in any position using installation technique and adhesives recommended in section
4.1.1.
Examples of Sensor installation points are shown in Fig. 2 for LV and MV circuit breakers. Fig. 3 and Fig. 4 show positions of the Sensors on the bus
stabs and cable connections inside LV switchgear, and MV switchgear, as
well as suggested positions of the sensors for measuring temperature of ambient air inside the cells.

Transmission Range: 100 ft. (sensors installed in switchgear).
Mounting Location: On flat clean surface using High T adhesive.
Transmission Frequency: Transmittance intervals change based on the
rate of the temperature change: Signal is transmitted by the Sensor every 12
minutes. However, in case of a temperature rise of 3º C per minute the Sensor will transmit every 6 minutes.
Battery: High temperature 3V lithium battery, easily replaceable in the field.
3.6. WTMS Receiver Features
The WTMS monitors all Sensors, actively measuring temperatures in a selected area. The Receiver constantly monitors and listens for transmissions.
The Receiver determines if a signal is valid or if it is noise to be filtered out,
then mark the transmissions with the proper packet and send it via a network
to a computer for processing.
The Receiver utilizes Spread Spectrum Technology (SST). It is available in
three different versions (Fig.5), plus a repeater version.
— Serial SST Receiver receives transmissions and sends them to a PC
via RS-485 using a Connection Kit (RS-485 to RS-232 Converter).
Serial REceivers to be connected, in series, for large coverage
areas.
— SST Receiver with wired Ethernet Connection (802.3).
— Wireless Extension SST Receiver, which provides wireless
transmission of the RF signals to a wired SST Receiver thus
doubling the distance between the transmitters and receiving units.
— Ethernet SST Receiver with Modbus TCP communication protocol.
Power must be supplied to the Receiver by using the power transformer
supplied with the Receiver. For the Serial SST Receiver, another option is to
supply power via the RS--485 network using power from the Connection Kit.
This option is ideal for a Receiver mounted in an area that does not have a
convenient power source.

Either the Serial or 802.3 Ethernet type of wired Receiver accepts
temperature and identification information from the Sensors and relays the
information to the TempAssure Software (see section 4.2), which displays
the activity of all wireless Sensors and logs their temperature readings into a
text file for future reference and analysis. A diagnostic screen allows the
user to monitor the system for any problems in the sensory network.

3.7.2 Ethernet SST Modbus® Receiver Connectivity
Ethernet SST Receiver with Modbus® TCP Protocol is equipped with both
an Ethernet port and an RS-485 Serial port, which allows using it as a Serial
SST Receiver. This function is provided to facilitate WTMS setup
preparatory procedure. This option could be utilized in optimization of
sensing and receiving units’ positions, while using a simple standalone
version of the system software. This version may be also used prior to
WTMS integrations into a customized monitoring system.
In Fig. 6, position of the ports for Ethernet cable and DC power input for
utilization of the Modbus® module are shown. The third port is designated
for connecting the Receiver to PC via connection kit (shown in Fig.10)
directly or using an optional Ethernet Serial Server. The use of Serial
module would require a connection kit and TempAssure software installed
on local PC. When the Serial module is utilized, the receiver will be powered
via a power supply that is included in the connection kit (the power input on

SECTION 4
WTMS INSTALLATION
4.1. Installation of Temperature Monitoring Hardware
Hardware of Wireless Temperature Monitoring System consists of the set of
temperature monitoring devices (wireless temperature sensors), signal receiving devices (Receivers) and connecting kit for connecting the Receiver
to PC and supplying power to the Receiver.
4.1.1. Installation of the Sensors
Use the following procedure to attach wireless Sensor to the part for which
the temperature is to be measured. The Sensor can be installed on any flat
surface made of metallic materials. The Sensor cannot be installed on any
movable contacts or lubricated areas.
Surface preparation note: If Sensors are installed on metallic surfaces on
current carrying part, on insulation, or on compartment doors, the surface
should be cleaned from any dust, particulate matter and moisture with a
clean dry cloth. If needed, use a mild cleaner to remove grease or dirt from
the surface.
Adhesives:
1. RTV Silicone Adhesive (requires about 24 hours curing at room
temperature), such as GE Silicone II Premium Waterproof Silicone,
stock number GE500 90642.
2. Instant adhesive (“super glue”) should hold the sensor in place long
enough for the silicon to cure. It is rated for about 125ºC (~260º F), so
© 2011 Schneider Electric All Rights Reserved
15
Wireless Temperature Monitoring System
Application Notes and Installation Manual
03/2011
the bus bar should be kept below this temperature during the curing
process.
The application procedure should be as follows:
Different views of the sensor are shown in Fig.7. It is pictured from the top
(left) and from the bottom (right), and the sensor case is shown in the
center. For installation, the units should be disassembled by removing the
lid and the sensor assembly (Fig.7) from the case. The case should be
glued onto the equipment surface with the bottom facing the surface. After
the sensor case is attached to the surface, the sensor assembly should be
inserted into the case with the copper enclosure getting into the opening in
the case bottom and the lid should be snapped in to close the case.
1. Apply a ring of silicone in the area between the outer edge of the small
elevated ring located at the opening in the case center and the edge of
case. The silicone ring should be about 2.5mm wide, enough to seep
around the case outside edges when applied (Fig.8, left)
2. Apply four drops of “super glue” equidistantly on the surface of small
elevated ring in the center to the case (Fig.8, right). As soon as the case
is pressed to the surface, the glue will spread and cover ~100% of the
ring surface area.
3. Attach the case bottom in the position on the surface of the part for
which the temperature is to be measured as soon as possible to avoid
an early hardening of the instant glue. Press the sensor to the surface
for 2 minutes, after which it is safe to leave the case for the next 24
hours to let the silicone cure. Super glue is strong enough to hold the
weight of the sensor in any position.
4. Make sure the silicone seeps around the edge of the sensor to prevent
airflow. After the cure is complete, the RTV silicone adhesive takes over.

4.1.2. Installation of the Receiver
Finding the best location for the Receivers:
The key factor in a successful install, is finding the best possible location for
the Receiver. The plant walk-through will provide best opportunity to search
for a location based on the sensor array. Place readers in open areas to receive as many signals as possible. Here are a few guidelines to help when
placing the Receiver:
•
Install the Receiver as high as possible
•
Position the Receiver in a central location
Place the Receiver as close to the center of the location as possible to
maximize the reception of the antenna. If a central location is unavailable,
look for the best possible sit in relationship to the sensors.
•

Wireless Temperature Monitoring System
Application Notes and Installation Manual
03/2011
The receiver is designed to work in noisy environments but it is hindered if
placed near (within 5 feet) the following devices:
— Florescent Lighting Fixtures
— Computers and Monitors
— TV’s and Radios
— Large Metal Objects
— Telephone and Network (Ethernet) equipment
— Other items that may block or absorb RF signals which may cause
blind spots to Receivers, such as thick concrete walls, airconditioning units.
Suggested mounting methods for Receivers: the Receivers should be
mounted with a minimum of 1 in. separation from flat surfaces such as walls,
rafters, etc. Steel walls and rafters especially require separation to get good
reception.
4.1. 3. Assembly of Connection Kit (Serial Receiver to PC connection)
Parts in Connection Kit:
1. DB25M-DB9F converter
2. RS-232 to RS-485 B&B converter
3. RJ45-DB25F converter
4. Transformer 120 VAC to 12 VDC
5. RJ45 cable (CAT5)
Assembly of Connection Kit
1. Attach the 9-pin connector of the DB25M-DB9F converter to Com port 1
(9-pin) on the back of the computer. If PC does not have 9-pin port use one
of USB ports with USB to RS-232 DB9 converter (not included).
2. Attach another end of DB25M-DB9F converter to the RS232 side of the
B&B converter. Connect the RJ45-DB25F converter to the RS485 end of the
B&B adapter. Connect the Receiver to RJ45-DB25F converter with RJ45 cable (use any of two lines on the bottom of the Receiver).
Assembled WTMS is shown in Fig. 10. If PC is located at significant distance
from the Receiver, use as long as needed RJ45 cord to connect the Receiver
to RJ45-DB25F converter. Otherwise use the cable included in the kit.
To energize the Receiver, connect the pin of power supply (transformer 120
VAC to 12 VDC) into the side of the RS485-RS232 converter and plug transformer into power jack. As soon as connection is made, the LEDs towards
the bottom of chassis of the Receiver begin flashing signalizing that the unit
receives RF signals from the sensors.

4.2.3 TempAssure Software Setup for Ethernet 802.3 Receiver
There is a specific version of TempAsure for the Ethernet Receiver. First,
you will need to run the Digi Device Discovery program to configure the
Ethernet Receiver to point to your TempAssure application. Lastly refer to
section 4.2.2. for the remainder of the setup, as most information still
applies to the Ethernet version.
4.2.4 TempAssure Reporting Software
The data from temperature monitoring system is transferred from the sensors
via the Receiver to TempAssure database. Standalone WTM System is working with TempAssure Software. The data collected by WTMS may be view
and analyzed using TAssure Local Report Program. LocalRpt is a reporting
tool used with the TAssure program to print a report and graph changes in
strobe temperature. LocalRpt also supports graphing of multiple Strobes for
easy comparisons between strobes. The Local Report requires that Sensors
and Receivers have names. Make sure that this has been done before starting Local Report. The first step in using the reporting program is to select the
sensor locations for the report. Click on the Show Item selection button (Fig.
16). This will display a list of sensor locations (items) to choose from. LocalRpt automatically selects
all of the items on the list by default. If you don’t want all items included on
the report, click on the Select None button and choose the specific items.
When making your selection you may select multiple strobes by holding
down the Ctrl key and clicking on each item. Then click on the Hide Item Selection Button.

Local Report: choosing the sensors for display
The next step is selecting the time frame for the report (Fig.17). Use the
Date/Time markers to select the starting and ending point. To increase or decrease the Date/Time use the arrow buttons next to the Date/Time you wish
to change.

To run a report for an allotted number of days you may click the Days button
and Input a value in the Report for Last ___ Days Blank.
The report is now ready to be created. Select the type of report to use. Select
the List button and LocalRpt will gather a list of strobe entries and display
them in a report format. To create a graph select the Plot button and LocalRpt
will create a line graph from the data recorded in the TAssure.log file. Listed
below are examples of the two types of reports. Shown in Fig. 18 is an example of the Plot type report, it creates a graph of the temperature for chosen
strobes.

The data may be listed if the option “List” is chosen, then the data may be
averaged for any selected time period and presented in tabular format. The
data may be exported into text file, which is easily converted into Excel
format for further analysis.
4.3. SCADA Software Integration
Most Supervisory Control and Data Acquisition (SCADA) and other
monitoring software package have a Modbus driver either “built-in” or
available as an option. In order to connect the Wireless Temperature
monitoring system via Modbus to a software package, the Modbus TCP
WTMS receiver will need to be utilized. The following steps should be
followed to establish communications with the receiver and create a device
tag within the SCADA software.
1. The WTMS receiver will need a static IP address. The unit comes preset
with a default of 192.168.0.100.
a. To configure the IP on the receiver, put your computer on the same
subnet as the receiver (via the IP configuration of your PC).
Important: Write down your settings before making the change.
(Fig.19)
b. Change the IP information on the receiver to work with your network,
by going to the receiver website and clicking “Edit” under network
settings. (See screen capture below) The website is located at
http://, and can only be reached if your
computer is on the same subnet as the device.
c. Change your PC IP settings back to the original settings you
documented in step (a).
Figure 19:
2. The receiver has a range of registers that store the information for each
sensor. The range starts at register 3801 and goes until 19800, with 20
registers allocated to each sensor.
Determine the sensor information that is stored at a specific register range
by going to the Sensor Mapping Page from the link on the main page of the

receiver. The table will only show entries for discovered sensors up to a
maximum of 800 entries.
A sample mapping page is displayed in the screen capture below (Fig.20).
The sensors are assigned a range by the receiver, as it detects them. The
first range of 290 registers is referred to as Table 1, and so forth.
Figure 20:
Following is a list of useful quantities and their offsets within the range of
registers assigned to each sensor:
Quantity
Sensor ID (two registers)
Offset
1 and 2
Celsius Reading in Hundredths of degree C
Fahrenheit Reading in Hundredths of degree F
14
Example:
To read the temperature in Celsius for Sensor ID 42154 displayed in the
above diagram, you would send a ModBus read request to address
157.198.172.61, specifying the 3825 (3821 + 4), as the register number
from which to read.
In the response packet you will get the temperature in hundreths of a
degree Celsius. So if the temperature is 25 degrees Celsius you will get a
ModBus response with the number 2500.
3. Clear the current sensor table by writing one to Modbus address 50000.
This will also clear the flash tables.
4. Acquire sensor channels.
5. When all channels have been acquired (verify the sensor mapping as
described in Step 2), write the sensor directory to flash by writing the
value “2” to Modbus address 50001.
NOTE: the flash write operation could take up to a minute depending on
the number of channels acquired, so leave the unit powered up.

VALIDATION TESTS FOR WTMS PARTS
AND PERFORMANCE
Square D Services designed and arranged a set of validation tests at
independent laboratories, and provided required documentation for the tests.

5.1. Validation Tests provided by Square D Engineering Services
5.1.1. Calibration Technique for Square D High Temp Sensors (direct
thermal contact with the surface)
Square D Engineering developed a new calibration technique providing sensor calibration in the conditions adequate to the system application. All sensors are calibrated within the oven with stabilized ambient temperature with
the sensors installed on the surface of metal bus, which temperature is
changing within the range of T from 0ºC to 150ºC and controlled with TCs.
5.1.2. Testing of Adhesion Quality of Silicone RTV as HT adhesive
Two different properties of high temperature adhesive have been tested to
approve an adhesive for using it for attachment of wireless temperature sensors in energized electrical equipment: (1) chemical inertness at high temperatures towards metallic and insulating surfaces, and (2) an ability to hold the
sensors in vertical or upside down position for the period in service. Testing
of Silicon RTV sealant at high temperature proved that the product provides
a good adhesion and is chemically inert towards the surface to which the
sensors may be attached. This adhesive leaves no residue on metal surfaces
of the bus or insulation after the sensors have been removed. Additional testing was provided by Freshloc technologies on Silicone adhesive strength.
The preferred adhesive was placed on a test bus bar and allowed to cure for
24 hours. The bus bar was then heated to approximately 150ºC for two
hours. At the end of two hours, the adhesive was tested to tolerate a load of
up to 20 lbs. The bond strength measure proved that the silicone adhesive is
sufficient to hold the weight of the sensor in vertical or upside down configuations.

5.1.3. Influence of High Voltage on Sensors Performance Signal Transmittance Test setup
The measurements have been conducted using HiPot Set providing high
voltage on the metal part using a Step-up VT that allows raising the voltage
up to 100 kV. Step-up VT is a source of corona by itself. Several Square D
High Temp sensors were positioned on piece of copper bus bar, which was
connected to Step-up transformer with the cable. The voltage has been
raised from 5 kV to 50 kV and held for 10 minutes at each voltage. At the last
stage of the test the voltage has been raised to 25 kV and was hold at this
value for one hour. During the test the receiver was in close proximity to the
Step-up transformer at the distance about 5 feet. During the runs with 50 kV
applied to bus bar corona occurred, which produced very strong sound. Multiple sensors have been located close to energized piece of bus bar to determine if their functions as well as performance of Receiver are affected by HV
corona.
Test Results
The effect of high Voltage and Corona in close proximity to the wireless sensors has been found insignificant.
