Battery Testing

They are designed for use together with TORKEL battery load units. Their purpose is to provide higher load currents for use in constant current or constant power tests. Together, TORKEL and the TXL extra loads form a system that can discharge batteries with currents of up to several kA. TXL extra loads are connected directly to the battery, and TORKEL measures the total current using a clamp-on ammeter.

The Megger BVM is a battery voltage measurement device that is used for the capacity testing of large, industrial battery banks commonly found in electrical power sub-stations, telecom facilities and computer data center UPS systems. When used in conjunction with a load device, such as the TORKEL unit, and test data management software, such as PowerDB and TORKEL Win, the BVM enables the user to perform a completely automated battery bank capacity test, according to IEC test method. The test also meets NERC/FERC requirements.

The BITE 2 and BITE 2P Battery Impedance Test Equipment determine the condition of lead-acid and nickel-cadmium cells up to 7000 Ah. An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions and more. The case of the BITE 2P consists of both the transmitter and a carrying case for all of the standard accessories and some of the optional accessories, in an all-in-one unit. The BITE 2 and its accessories fit into a sturdy canvas case with a shoulder strap.

The Megger BITE3 Battery Impedance Test Equipment determines the health of lead-acid cells up to 2000 Ah by taking measurements of the most important battery parameters. The BITE3 measures cell impedance, an internal ohmic test, cell voltage, intercell connection resistance and ripple current. And, for the first time in a battery instrument, the BITE3 measures float current and the harmonic content of the ripple current. There is even a built-in spectrum analyzer to show the harmonic content of the ripple current. It has firmware that can be upgraded through the Internet and supports multiple languages.

The BITE Receiver is a direct replacement for the standard receiver supplied with the original BITE. It provides data storage capabilities without having to replace the BITE transmitter.

The receiver incorporates the potential leads, clamp-on current sensor, and data storage capabilities in one unit. The unit stores more than 2000 sets of data (cell impedance, cell voltage and interconnecting strap resistance).

At any time during a test, the operator can review the current test results by using arrow keys and scrolling back through the active test screen. If needed, the operator can retest any of the cells and straps in the current test.

Stored data also can be downloaded via the RS-232 connector directly to a personal computer.

Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger new heavy duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.

The MEGGER DUCTER DLRO10 and DUCTER DLRO10X bring new standards to low resistance measurement. Both are fully automatic instruments, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1 to 2000 on one of seven ranges. For users who desire more control over the measurement process, DLRO 10X uses a menu system controlled by a two-axis paddle to allow manual selection of the test current. DLRO10X also adds real-time download of results and on-board storage for later download to a PC.

The BT51 Low Resistance Ohmmeter makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The test current is maintained at a nominal 2 A, and as the measurement is ratiometric, the reading is unaffected by any current variations.

The Megger TTR25-1 is an automatic hand-held battery operated transformer turns ratio test set.

It is used to measure the turns ratio, excitation current and polarity of windings in single- and three-phase distribution and power transformers (tested phase by phase), potential & current transformers, and tapped transformers.

This instrument was developed to detect, track and locate ground faults on battery systems - without resorting to sectionalizing! Model BGL tracks and locates ground faults on live or dead battery systems. To save hours of unnecessary troubleshooting, the BGL readily differentiates between the resistive fault currents and capacitive charging currents. This feature allows the instrument to detect and track leakage paths, even in the presence of surge-suppression capacitors.

The Single Phase TTR, Transformer Turns Ratio Test Set, measures the turns ratio and exciting current of windings in power, potential and current transformers. Deviations in turns ratio readings indicate problems in one or both windings or the magnetic core circuit.
