T&R 750ADM Mk4 Primary Current Injection Test Set
The compact and rugged T&R 750ADM mk3 is a flexible current injection system capable of supplying currents of up to 750A AC into a variety of loads. The unit is designed for testing devices used for power system protection, but can be used wherever a high current AC source is required.
With a maximum voltage of 5V, this unit is ideally suited to all low power primary injection tasks requiring up to 750A for short periods. The PCU1-SP and PCU2/E systems have separate control and loading units, allowing a wide range of load conditions to be covered with different loading units.
(Where higher currents and powers are required for primary injection... 7kVA and 20kVA primary injection systems are available)
T&R 750ADM Accurate Metering / Flexible Timing:
- Two outputs - allow injection of currents as low as a few hundred milliamps and up to 750A
- 40A output - allows voltages up to 16V (higher impedance trips can be tested)
- Four true RMS metering ranges - allowing the full scale of the meter and trip level to be set independently of the selected output
- Capture time of less than 20ms - allowing the RMS of a single cycle to be accurately measured
- Industry standard connectors - for convenience, reliability and safety
- Comprehensively protected by electronic overcurrent and thermal trips
- Flexible timing system - allowing trip times, reset times and reclose times to be quickly measured to a high degree of accuracy
- Two contact inputs - each of which may be triggered by a volt-free contact or a dc voltage
- The contact inputs auto-sense for normally open or normally closed contacts
