50ADM-P Current Injection System with Phase Shift

0-50A output current True RMS metering with 1 cycle capture Variable auxiliary AC voltage/current output with phase shift Auxiliary metering input V, f, φ, Z, P, S, PF, CT ratio, harmonics Variable auxiliary output 12-220VDC Multi-function auto-range timing system Current limit mode for fine control Data storage to USB memory key including waveform & harmonics USB keyboard interface Automatic mains voltage selection Optional Backpack System The 50ADM-P is a smaller version of our current injection system the 200ADM-P. The unit has a range of outputs allowing injection of currents from 1mA to 50A. Voltages up to 18V are available on the main outputs. True RMS metering with single cycle capture is provided. Three 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 50ADM-P has a flexible auxiliary AC output that can be used at 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 input is provided that meters AC and DC voltage, current and frequency from the auxiliary outputs or external signals. The mod-ule can also take measurements in conjunction with the main current output to meter phase angle, power, impedance, CT ratio and harmonics. A variable stabilised DC supply with current limit is provided to power the relay under test. The unit has a comprehensive timing system linked to the outputs allowing 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 key and keyboard. Results of every test can be stored to the memory key 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 key. Harmonic analysis results can also be recorded.
