PCU1SP mk2 - Primary Current Injection (Up to 5000A, 11.5kVA)

Click on Image to Enlarge

The PCU1-SP mk2 is medium powered primary current injection systems 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. The PCU1-SP mk2 are ideally suited to primary current injection, stability testing and circuit breaker testing.

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.
