T&R 200ADM-P Current Injection Relay Test Set
T&R designed the 200ADM-P Current Injection Relay Test Set for secondary current injection and relay testing. Its main output supplies currents up to 200 A, while four output taps let users select voltages up to 240 V to suit different current requirements. The unit can also provide a high-current AC source for suitable test applications.
True RMS digital metering, a memory ammeter and a multi-function timing system support accurate testing. When the timer stops and the output switches off, the instrument holds the current reading on its large back-lit liquid crystal display. The T&R 200ADM-P also supplies auxiliary AC and DC outputs, an auxiliary metering input and a clear user interface to simplify practical test operation.
For test records, users can save displayed values to a spreadsheet file on a USB memory key, while the real-time clock adds a time and date stamp. Users can also add comments through the unit controls or a compatible USB keyboard, and the USB interface can support a printer. The T&R 200ADM-P combines these recording functions with automatic mains voltage selection, output protection and a compact, portable design.
Key Benefits
- Delivers up to 200A AC, providing the high-current output required for supported relay and protection testing.
- Four main output taps allow the output voltage and available current to be matched to different test requirements.
- True RMS digital metering provides direct current measurement, while the memory ammeter holds the reading after a timed test ends.
- A multi-function timing system supports controlled test work without the need for a separate basic timer function.
- The large back-lit liquid crystal display helps users view test information clearly during operation.
- Auxiliary AC and DC outputs provide additional test and device-powering options from the same test set.
- Auxiliary metering supports measurement of voltage, current, frequency, phase and harmonics, with power and impedance measurement also supported in conjunction with the main current output.
- USB result storage allows displayed values, waveform information and harmonic data to be retained for test records and plotting.
- Electronic over-current protection, duty-cycle trips, thermal monitoring and fused circuits protect the unit during use.
- Automatic selection between the stated mains supply ranges simplifies connection to the appropriate supply.
Common Applications
T&R 200ADM-P Current Injection Relay Test Set is suitable for a range of testing, maintenance and inspection tasks, including:
- Secondary current injection testing.
- Relay testing.
- G59/G99 protection testing.
- Power system protection device testing.
- High-current AC source applications.

Why Choose This Model?
The 200ADM-P combines output currents up to 200A with True RMS metering, timing, auxiliary outputs and test-result recording. The supplied information for the other named models only confirms accessory compatibility, so no further verified performance comparison can be made.
