HV Diagnostics 200ADM-P Current Injector 

HV Diagnostics 200ADM-P Current Injector

200ADM-P is a current injection system with a wide range of advanced features including phase shift, data storage and harmonic analysis.

The unit has a range of outputs allowing injection of currents between 1mA and 200A. Voltages up to 240V are available on the main outputs allowing high impedance current relays to be tested. True RMS metering with single cycle capture is provided. 4 current ranges allow the full scale of the meter and trip level to be set independently of the selected output. Industry standard safety connectors are used throughout for safe, reliable convenience.

The unit has a comprehensive timing system linked to the outputs allow trip times, reset times and reclose times to be quickly measured to a high degree of accuracy. The timer includes a current operated mode and can accurately test instantaneous trips.

Two USB host sockets are provided to connect a memory stick, keyboard or printer. Results of every test can be stored to the memory stick in spreadsheet format for later analysis. The keyboard allows entry of a comment against each result. In addition, a graphics file of the waveform may be stored to the memory stick. Harmonic analysis of results can also be recorded.

The 200ADM-P has a flexible auxiliary ac output up to 260V for voltage relays or up to 10A for current relays. The phase and frequency of this output are fully adjustable. This combination of voltage and current allows testing of relays that require two voltages, one voltage and one current or two currents.

An auxiliary metering module is provided that meters ac and dc voltage, current and frequency from the auxiliary outputs or external signals. The module can also take measurements in conjunction with the main current output to meter phase angle, power, impedance, CT ratio and harmonics.

A variable stabilized DC supply with current limit is provided to power the relay under test.
