STSGGROUND GRID TEST ACCESSORIES KIT

eKAM test system includes two portable units: one control unit

with a large graphical display that adjusts the AC voltage output

(up to 220 V) and one current unit (up to 2000, 3000, 5000A).

BUX 2000 (2000 A) - BUX 3000 (3000 A) - BUX 5000 (5000 A):

one or more BUX current unit can be connected to eKAM (not

simultaneously), they can be ordered separately when the order

is placed or at a later moment.

With the control knob and the LCD display, it is possible to en-

ter the MENU mode, that allows to set many functions, making

eKAM a very powerful testing device, with manual and auto-

matic testing capabilities and with the possibility to transfer test

results to a PC via ETHERNET or Pen Drive.

The TDMS software, which comes with the test set, allows to

download, display and analyze test results obtained in local

mode. Remote maintenance and diagnostic of the instrument

are available via Ethernet. TDMS software operates with all Win-

dows® versions. The ease of operation has been the first goal of

eKAM. This is why the LCD display is so large and the dialogue in

the MENU mode is made easy.

eKAM includes three measurement inputs:

. DC voltage (10 V DC).

. AC voltage:

.. High range (300 V AC)

.. Medium range (10 V AC)

.. Low range (3 V AC)

. Current (10 A AC or DC).

All these inputs are independent among them (unless 3V and

300V) and allow the measurement of CT outputs or of another

source. In addition, a digital input (up to 300 V) is available: it

can measure the timing of a wet or dry contact. The instrument

is housed in a transportable aluminium box, which is provided

with a cover and handles for ease of transportation. A transport

case can also be supplied upon request.

IEC 61850-9-2 Sampled Values

eKAM has the facility to test CT, both conventional and non

conventional, Merging Unit (MU) using the IEC 61850-9-2 (SV)

protocol. eKAM generates current signal and injects these quan-

tities into the CT under test. eKAM then reads the data from

the network (Sample Values) in order to perform a variety of

different tests.

. Possibility to test CT ratio and polarity check up to 2000 A,

3000A and 5000A. Test of MU.

TDMS – Test & Data Management Software

TDMS, Test & Data Management Software, is a powerful soft-

ware package providing data management for acceptance and

maintenance testing activities. Electrical apparatus data and

test results are saved in the TDMS database for historical results

analysis.

The TDMS database organizes test data and results for the ma-

jority of electrical apparatus tested with ISA test sets and related

software.

PADS - Power Apparatus Diagnostic Software

PADS - Power Apparatus Diagnostic Software is a powerful soft-

ware application, included in TDMS software, that optionally al-

lows the remote control of the eKAM and STS family: STS 5000,

STS 4000, STS 3000 light and TDX 5000. The software performs

various tasks, such as:

. Controls eKAM from PC

. Create test plan

. Download stored test results via Ethernet cable

. Create and customize test reports

. Print test results

This program runs under Windows© environment.

Note: Windows is trademark of Microsoft Corporation.

TEST PLAN EDITOR is an innovative and advanced software

module allowing the operator to define and plan a sequence of

tests. The operator defines the desired sequence of tests and

sets the parameters of each test. TEST PLAN EDITOR creates a

sequence of tests to be performed automatically. This feature is

available for the test of current transformer. It is also possible to

create a test sequence for primary injection.

At the end of the programming, starting the first test will ex-

ecute the complete sequence. During the test, test results are

stored in the memory. The test set minimizes the test Test plans

can be saved or recalled, like test results. Up to 64 settings can

be stored and recalled. Settings are permanently stored in the

memory and new settings can be written to the same address

after confirmation. During the test, test results can be stored in

the memory. At the end of test, settings and test results can be

transmitted to a PC provided with TDMS. The software allows

saving, exporting and analysing test results

• CT RATIO, POLARITY AND BURDEN

The ratio measurement is performed applying high current, coming

from one of the BUX modules, to the CT primary and measuring the CT

secondary current. The burden can be by-passed, or left in series for the

measurement. In this instance, the voltage drop is measured. The secon-

dary current can be measured by a clamp. Input parameters are: the

nominal primary and secondary current, from which the program com-

putes the nominal ratio and the nominal test current. The display shows:

• The actual primary current

• The corresponding secondary current

• The value of the secondary current with the nominal primary current

• Actual ratio and ratio error

• Phase shift and polarity.

When the burden is tested, the following parameters are displayed:

• The voltage drop across the burden;

• For the burden: VA rating at the nominal current, angle and power

factor.

• CB; PRIMARY AND SECONDARY RELAY TESTS

The selection allows injecting the test parameter and measuring the

relay threshold and trip delay of a MV CB or of a relay. It is also possible

to measure external voltages and currents. Accordingly with the BUX

model, it is possible to perform high current tests, up to 5000 A. Input

parameters are:

• current range

• output current

• frequency.

It is possible to enable the time measurement on the digi-

tal input and to set the type of digital input (wet or dry).

The display shows the following data:

• Test current or test voltage • Trip time • Closing time • External volta-

ge and current measurements.

GENERATOR OUTPUT

The internal generator has one high power - AC voltage output, not

insulated from the mains. The adjustment is performed by the local

control.

The generated frequency can be userdefined or synchronized to the

supply frequency (with optional power line synchronizer). The following

specification applies to the output.

NOTE:

. Output power is reduced with the supply of 110 V.

. Output amplitude may decrease for frequency below 50 Hz and above 60 Hz.

Output frequency

. AC output frequency range: 15÷500 Hz.

. Frequency resolution : 10 mHz.

INPUT MEASUREMENTS

Current and Voltage

It is possible to meter the current and the voltage of an external

input. Three metering groups are available:

. AC or DC current, up to 10 A

. AC voltage, with two connections:

o High range, up to 300 V AC.

o Low range, up to 3 V AC.

. AC/DC voltage up to 10 V DC.

Binary Input - Timer

The test set allows tes ng protec on relays. The test current

or voltage can be ramped or stepped. As the output changes, a

the relay has tripped or the output cut is cut. Characteris cs of

the Digital input:

• The input may be selected as Normal Open, Normal Closed

• The  mer can start from an analog input ( current or voltage)

• The  mer can start and stop at the changing of the digital

input, both dry or wet contact

• Type of input: either dry or under voltage. Maximum input:

300 V AC or DC

• Voltage thresholds: 5 V, 24 V, 48 V or > 80 V
