T&R 50ADM-P 50A Secondary Current Injection Test Set
The T&R 50ADM-P is a smaller version of the T&R 200ADM-P current injection system. The unit has a range of outputs allowing injection of currents between 1mA and 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. A variable stabilised DC supply with current limit is provided to power the relay under test
The T&R 50ADM-P 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 sockets are provided on the T&R 50ADM-P 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.
The T&R 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 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.
