Brand T&R Test Equipment

The T&R PCU1-SP mk2 is a medium powered primary current injection system offering output currents up to 5000A (11.5kVA for 40seconds). The system consists of a separate control unit containing all metering and control functions and a loading unit that provides the high current output. In addition, the SP version offers direct-reading CT ratio and polarity tests and a 100A secondary injection output.

Two loading units are available, delivering a maximum output current of 2000A or 5000A. Each loading unit has three output taps to allow for a wide range of load impedances. For example, the NLU5000 may be configured to either give a maximum current of 5000A on the 2.3V range, 2500A on the 4.6V range or 1250A on the 9.2V range.
