The 200ADM-P Mk2 Secondary Current Injection Test Set is a versatile testing solution that enables users to inject currents ranging from 1mA to 200A. The device’s main outputs can produce voltages up to 240V, making it possible to test high impedance current relays. Instrument features true RMS metering, which provides single cycle capture, and users can set the full-scale meter and trip level independently of the selected output with four current ranges.

To ensure safety and reliability, the device uses industry-standard safety connectors throughout. The 200ADM-P Mk2 also has a flexible auxiliary AC output that can adjust phase and frequency and be used up to 260V for voltage relays or up to 10A for current relays. The auxiliary metering module allows AC and DC voltage, current, and frequency measurement, and it can take measurements with the main current output to meter phase angle, power, impedance, CT ratio, and harmonics. Additionally, the device features a variable stabilized DC supply with current limit to power the relay under test.

The device includes a comprehensive timing system linked to the outputs, allowing quick and accurate measurement of trip times, reset times, and reclose times. The timer features a current operated mode, which accurately tests instantaneous trips. The instrument also has two USB host sockets for connecting to a memory key, keyboard, or printer. Users can store the results of every test in spreadsheet format on the memory key, along with a comment against each result. They can also store a graphics file of the waveform and record harmonic analysis results.

Overall, the 200ADM-P Mk2 Secondary Current Injection Test Set offers a versatile and reliable testing solution for high impedance current relays, voltage relays, and current relays. Its advanced features and safety measures make it a suitable choice for accurate and efficient testing.
