S1/2, MIT5/2 and MIT10/2 series Contents Taking the lead for safety! As an essential aid to safer testing, Megger has introduced a new and comprehensive family of test leads for use with its insulation resistance testers. Three metres long, and made from ultra-flexible silicone-insulated cable to ensure long life, the new leads cover virtually all requirements related to insulation resistance testing at up to 10 kV. For use in applications where the space for making test connections is not restricted, the test leads are fitted with large insulated clips. They have a maximum jaw capacity of 34 mm, and an insulation rating of 10 kV. For applications where space is more restricted, but a useful level of protection from the output of the insulation tester is nevertheless required, the range includes leads that incorporate medium-sized insulated clips. With an insulation rating of 6 kV, these leads have a maximum capacity of 18 mm. In some instances, such as motor terminal boxes, space for connecting the test leads is so restricted that insulated clips cannot be used. For these applications, Megger offers test leads with uninsulated clips that have a maximum capacity of 18 mm. Leads with large, medium and uninsulated clips are supplied in colour-coded sets of three – positive, negative and guard. Also included in Megger’s new test lead family are leads designed to allow insulation resistance testing to be carried out more safely on low voltage control circuits in the vicinity of high voltage equipment. With insulation rated at 1 kV, these leads are supplied in sets of two, and incorporate probe-type tips with push-on crocodile-clip adaptors. 5 kV and 10 kV insulation testers Megger has up-rated the safety of its 5 kV and 10 kV insulation resistance testers to CATIV 600V and changed the test leads it supplies in the kit. 1965: First low-voltage insulation power factor set, weighing less than 6.5 kg Advanced manufacturing technology 1980: First semi-automatic 2.5 kV and 10 kV insulation power factor test set Megger believes that the best way to secure good quality products and intellectual property is through excellence in engineering and its production facilities. 1990: First fully automatic 10 kV insulation power factor test set Advanced manufacturing technology including automated wave-solder machinery and robotic surface mount component technology help keep costs down and quality up.

This allows easier and quicker pre-location and pinpointing of the unstable faults. CABLE FAULT LOCATION 17 Time domain reflectometers Time domain reflectometry – or TDR for short – is based on the simple notion of reflecting an electrical signal from the fault back to your instrument, and measuring the time. Megger has taken the concept, and added easy to use diagnostic tools that help even inexperienced staff make expert assessments. These instruments are used to locate the exact route and depth of metallic cables. The instruments’ capabilities are enhanced by offering both passive and active modes. For ease of use, and improved efficiency, the instruments can be either inductive or conductively coupled. Single channel cable fault locator A state of the art TDR capable of identifying and locating faults on metallic cables. The TDR1000 is suitable for use on both dead or live cables without a blocking filter, up to CATIII 300 V phase-to-earth. ■ Multiple output frequencies* ■ Variable tx output power level* How TDRs work Problems with the dead zone The width of the transmitted pulse affects the TDR’s ability to identify reflections. The width of the pulse is sometimes referred to as the dead zone. As the pulse increases in width, it becomes more difficult to identify reflections, because the dead zone may mask closely spaced reflections. The TDR measures the time it takes a pulse to travel down a cable, encounter an impedance change, and reflect back. By knowing the velocity of the pulse the TDR converts this time to distance. Velocity of Propagation Pulses travel at different velocities on different cables. The type of insulation and cross sectional area of a cable will affect the velocity of a pulse. The velocity of a cable can easily be determined by connecting onto a sample of known length. Place the TDR’s cursor at the reflection representing the end of the cable. Adjust the velocity setting until the unit reports the correct length. This setting will be the velocity of propagation for the cable. When the problem has been identified, it can be corrected easily, certainly faster, and more efficiently than rewiring the system. L1050, L1070, L1071 Accutrace, and Cable Route Tracer Portable cable locators TDR1000/2P A TDR measures the time it takes a pulse to travel down a cable, encounter an impedance change, and reflect back. By knowing the velocity of the pulse the TDR converts this time to distance. You can then pin-point the exact location of the problem. Using a Time Domain Reflectometer (TDR) such as TDR1000/2 you can find the distance from the tester to the end of the wire (up to 3,000 metres), along with the distance to each anomaly within the circuit. The problem could be in a terminal block, a wire bundle, or a poor connection. Cable trace and voltage detectors Capable of locating long or short ranges, inductive or conductive, active or passive, the L1070 delivers quick and accurate results with a user-friendly interface ■ Peak and null detection* TDR2000/2P A state of the art mono or colour display two-channel TDR. capable of identifying and locating faults on metallic cables. The TDR2000P is suitable for use on dead or live cables without a blocking filter, up to CATIII 300 V phase-toearth with a range of up to 20 km.

If a second detector is added, the set will also display the direction to the fault. Voltage detectors are suitable for voltages from 2.3 kV to 550 kV. Models are available with electronic LED and audible indication or neon indication. Phasing testers are available from 2.4 kV to 69 kV with a choice of analogue or neon voltage indication. TDR2000/2P can identify and locate a wide range of faults on metallic cables from a few metres to 20 km depending on cable type DETEX Voltage detectors are available in seven models that cover a range from distribution class to transmission line voltages up to 550 kV Cable Fault Pinpointer MPP1000 series locators are used to pinpoint faults in shielded, direct buried cables by detecting both the electromagnetic and acoustic pulses emitted from an arcing fault when it is surged. ■ Push button depth measurement* It takes less time to train users on TDR1000/P, as each key has a dedicated function, such as cursor left and right, velocity factor, range etc. MPP1000 The MPP1000 is the accurate way to pin-point a fault on buried cables The MPP1000 series of locators can be used with any surge generator. New Single-phase time domain reflectometer Primarily used for the pre-location of cable faults using arc reflection, differential arc reflection and impulse current methods, the MTDR1 offers exceptional flexibility yet is intuitive to use with facilities such as operator assist, autoranging and auto distance to fault. With a full built-in keyboard and Windows® XP operating software the MTDR has a range of up to 30 km. Megger designs and lays out its own printed circuit boards.

TRANSFORMER TESTING 21 Transformer testing Transformer testing Transformer ohmmeter MCT1600 Transformer winding resistance and tap-change test set Current transformer tester A robust, portable unit to automatically or manually perform saturation, ratio, polarity, demagnetising tests, CT burden and insulation tests on current transformers using the voltage comparison method. It has an integrated 1 kV insulation test system. The colour display is viewable in daylight and shows multiple instantaneous saturation curves with knee points. Data is saved to a USB stick. Field portable low resistance measuring instrument designed to test transformer windings, motors, generators and tap changers. The two independent measuring channels greatly reduce the test duration of large inductive loads like transmission transformers, where it is possible to measure secondary and primary windings simultaneously. MCT1600 has a manual voltage output control knob. The user can perform any test required manually if only a spot check is needed. A lightweight, field portable unit that safely and accurately measures the DC winding resistance of all types of transformers and rotating machines MTO320 MCTT-10 Current transformer tester MCTT10 is a portable unit for performing saturation and ratio tests on current transformers using the voltage-comparison method. It provides a variable voltage output and precision instrument for testing single and multi-ratio CTs. Saturation and ratio tests can be performed without changing any leads. Current transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. However it is necessary for the equipment to be totally isolated from the electrical system prior to testing. New Transformer ohmmeter with graphical interface MTO210 New Transformer ohmmeter MCTT-10 performs saturation and ratio tests on CTs using the voltagecomparison method New MTO210 is a line-operated, field-portable instrument designed specifically to measure the d.c. resistance of all types of magnetic windings safely and accurately. It is mainly used all types of transformer windings but can also test rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits. Three features combine to make this instrument unique ■ dual measurement ■ load tap-changer testing MTO320 provides a fully automatic six-winding resistance measurement capability, even on 3-phase transformers with tap changers. During tap changes, the unit also continuously monitors for any break-before-make conditions. The high contrast bright 5.7” full VGA colour display can be clearly read in direct sunlight. The graphical user interface allows automated setup and control through easy-to-read icon based screens. The full QWERTY keyboard speeds the entering of information such as nameplate-type data. Communications is via RS-232, USB and Ethernet ports for easy on-board printing and storage, and downloading of test results. ■ safety shutdown Once testing is complete, the unit will automatically demagnetize the transformer. The dual set of potential inputs measure the resistance of the primary and secondary windings of a single- or three-phase transformer simultaneously speeding up the measurement. Supplied with PowerDB LITE PC software application, the user can perform data analysis and trending of results. To achieve a tenfold improvement in reading time, a balancing current is applied to the secondary to attenuate the circulating current induced when the test current is applied to the primary winding. TTR550005 Single-phase transformer turns ratio test set The single-phase TTR measures power and distribution transformers using the manual balancing method. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit. A hand crank provides power for the TTR550005. When testing the windings and contact resistance on tapchangers with make-before-break contacts and voltage regulators, the internal shutdown circuit of MTO210, which will be triggered by a voltage kickback of a few microseconds if the tap-changer contacts are opened, can be used to check for pitted or misaligned contacts as the instrument will shut down if either condition occurs.

The insulation properties can change due to oxidation, acids, sludge, gas and water absorption. These changes can be monitored using a dielectric Megger OTS test set. Karl Fischer testing uses the titration method to measure the amount of water in fluids such as insulating oil. It has become a standard test done on transformer insulating oil. KF875 Portable moisture in insulating oil test set OTS100AF/2 Easy to use, portable one button test set with integral printer. Can be powered from mains, internal rechargeable battery or car battery.

They indicate any restrictions in current flow that might prevent a machine from generating its full power or allow insufficient current to flow to activate protective devices in the case of a fault. Periodic tests are made to evaluate an initial condition or to identify unexpected changes in the measured values, and the trending of this data helps indicate and may forecast possible failure conditions. Excessive changes in measured values point to the need for corrective action to prevent a major failure. Ask for the free Megger guide to low resistance testing. This 32 page comprehensive guide is written in a clear, easy to read style. The booklet comprehensively covers both theory and practise. It has chapters on how to measure low resistance, choosing a low resistance tester, and evaluation and interpretation of results LOW RESISTANCE TESTING 27 Battery testing Battery testing BITE2P With the increasing dependency of back up systems on battery strings, and the escalating cost of replacing failing cells; instrumentation and software systems that can measure trend and manage the life-cycle of cells is a cost effective option. Are batteries a waste of time and money? Batteries are indeed, a waste of money. This means to say that if the power grid were 100% reliable, batteries would not be necessary! The many worldwide power outages over the past several years make batteries essential as a backup source. Who actually gives batteries a second thought? We simply expect them to work when called upon. Experience has shown that this expectation is pure fiction. Batteries are extremely important to provide electricity to support many assets and revenue streams during outages. For example, in a generating station, if the turbine suffers an outage, without the back-up battery the turbine lube oil priming pumps would not continuously keep the bearings lubricated causing major damage and lengthy outages. In hospitals, who wants to be in the middle of an operation when an a.c. outage occurs without proper battery back-up? The applications for batteries are innumerable and frequently unseen. In this world of dependency upon electricity, it is impossible to survive without battery back-up. It is not enough to only check the voltage and specific gravity. The sum of all of the cells’ voltages equals the charger output. Voltage (and specific gravity) of lead-acid batteries follows the sulphate. If a battery is fully charged, the sulphate will be in the acid and its voltage and specific gravity will be normal (with few exceptions.) If it is in a discharged state, the voltage will be low and as there will still be some sulphate on the plates, the specific gravity will also be low. If the battery has a normal voltage, there is no indication of its condition. When the voltage is abnormal, it may indicate a potential problem. There are many failure modes for batteries. With care and measurement these can be dramatically reduced, especially if little to no testing is presently being performed. The battery is installed, not to add to work load, but to support critical electrical equipment or revenue streams. Proper testing and data analysis can help determine when a battery should be replaced. Testing also helps reduce emergency battery replacements and assists in budgetary planning, thus reducing cost. A properly implemented battery testing regime does not necessarily reduce the work load but it will, most likely, increase reliability of the entire d.c. network. 28 BATTERY TESTING BITE 2P Battery Impedance Test Equipment determines the condition of lead-acid and nickelcadmium cells up to 7000 Ah BITE® 3 A rugged durable instrument whose enhanced capabilities make it easier to determine the true state of health of a battery system, terminal plate to terminal plate.

It is particularly effective in a high electrical noise environments, as the strength of the test current can be adjusted Battery earth fault trace A manually balanced instrument that identifies, tracks and locates ground faults in unearthed d.c. battery systems, on-line. Effective in high electrical noise environments, as the strength of test current can be adjusted. Useful for industries where power supply for operating measurement, communication and control equipment is critical. This instrument detects, tracks and locates earth faults on battery or floating systems by injecting a 21 Hz or 25 Hz signal (depending on line frequency) between the system and earth. The resulting current is then traced through the system with a clamp accessory, knowing that the fault current will flow to earth until the fault is located. Designed for operation on live battery systems, hence there is no requirement to isolate the system. BGL simplifies fault tracing by identifying fault characteristic (resistive and capacitive) magnitudes BATTERY TESTING 29 Earth ground resistance testing Megger has more than 50 years experience of designing and building earth resistance testers.

The software is designed from a ground-up approach, and is easily the most advanced package on the market. It employs over 160 industry standard test forms that have been developed and used by industry specialists during the last 20 years. The software package provides data management for electric utility companies, electrical testing services acceptance jobs, or maintenance testing jobs. Data entry, storage and creating reports are all features of the software. In a single step, PowerDB is able to quickly create entire test documentation packages that include test reports, comment and deficiency summaries, table of contents and field service reports. In addition, users are able to use this flexible software to define data forms and customize them to different device types. PowerDB’s test forms are designed to be used with each of the following Centres: Batteries Cables Circuit Breakers Coordination Data Disconnects Generators Ground Fault Tests Ground Mat/Grid Tests Instrument Transformers Power Transformers Insulation Fluids Loadbreak Switches Motor Control Power Factor Tests Relays Switchboards Transfer Switches Watthour Meters Transducers Easier Management of Test Data This easy-tooperate software offers a straightforward approach to data management. The first basic step in creating this userfriendly package was to make test data entry screens and printed forms identical. Users will appreciate that what they see on the screen is what they will see in the printed version. PowerDB also simplifies testing and data management by allowing users to deliver reports electronically using e-mail, CD-ROM, web server and PDF files. The software will also execute several tasks for the user, including equation calculations, temperature correction factors and charting. PowerDB helps predict possible equipment failure by trending previous results, which can be stored using PowerDB or imported from other software. This makes transitions from other software to PowerDB easy, and users can be prepared for possible problems with equipment. The industry standard test form is not always what a company needs, and because of that, the PowerDB software allows the user to customize forms. With a drag and drop feature anyone, even those without database experience, can create a form simply by dragging and dropping in tables, text boxes, images, charts and more, to create a customized form. And, with VBScript, calculations can be defined, tables looked up, and it can even interact with other applications. One time definition of common items can be used to put logos, headers and footers on every page or in many multiple forms. One change will automatically update every form the common item is used in. There are three ways to document testing using the PowerDB software. First, the software can communicate directly with test and measurement equipment produced by Megger. This allows these products to enter the results Test and measurement software directly into data fields. Second, forms can be filled in using other applications, including Megger’s Advanced Visual Test Software, entering data into the fields using information stored in the other applications. Finally, data fields can be filled in using manual entry. This allows the user to enter the exact information that is desired. Built-in Report Flexibility PowerDB can create reports in one step, with customizable sorting of the order of test forms. Forms can be removed, and Computerized Maintenance Management System Support Many electrical utilities and other company operations have invested in sophisticated CMMS systems, such as Digital Inspection’s Cascade and MRO Software’s MAXIMO. However, due to test instrument specific software packages and handwritten test results, these firms often struggle to get test data into their systems. One electric utility even referred to getting data into the CMMS as ‘feeding the monster’. PowerDB’s speciality IS ‘feeding the monster’. PowerDB allows you to link easily with the CMMS system so that the system can pre-populate the PowerDB equipment database, send PowerDB all work orders, add forms based on the job plans, and even return the measurement points, obtained from a multitude of test sets, back to the CMMS system. page numbering will be automatically adjusted. In a single print job, supplemental reports can also be printed at the same time as the primary report. The supplemental reports, including comment and deficiency summary reports, open up the data and information for all of the equipment tested on one job. Finally, all of the information can be generated for the on-demand world using the optional PowerDB Web server. All of the user’s important information is published to the Web and can be accessed from anywhere in the world. Furthermore, Megger will work directly with your CMMS personnel to integrate your data into your internal CMMS system. well-suited for technicians who prefer to spend a minimum amount of time writing reports and want a more concise way to process data. Simplifying the Compilation and Reporting Process The new PowerDB software package eliminates many common paperwork and recording problems. With the software, the number of man-hours devoted to preparing reports will be minimal. The user can customize the reports to be what a job requires but will not have to write the report, which is automatically generated by the software. Included in the reports are a table of contents, data sheets, as well as comment and deficiency summaries. PowerDB even comes with a built-in spell check. Electronic records of test data can create a couple of different problems for companies and utilities. While many electronic records are hard to locate due to the vast amount of records kept on one system PowerDB makes it easier. By using its relational database it is much easier to find present and past records. And, because it has multiple safe guards, PowerDB prevents lost data. By saving documents that are in progress to multiple places, the problem of lost data is eliminated. PowerDB also synchronizes the date to several machines, meaning that a single crash does not create a costly loss of data. Automatically generated professional reports means that a testing company, for instance, is able to complete jobs faster and in a more efficient manner.
