T&R PCU1-SP mk2 Primary Current Injection System

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. FEATURES 5kA maximum output current (higher overload currents for 2s). Multi-function digital timing system. Digital true RMS memory ammeter. Solid state switching. 200A, 2000A and 5000A loading units. Three range outputs on loading units. Rugged, compact design. Optional trolley mounting of system. Secondary injection up to 100A. Auxiliary metering input.
