Product Description
The PCU1 series are medium powered primary current injection
systems offering output currents up to 5000A. 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-LT and PCU1-SP 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. T&R also offer the
higher-powered PCU1-HP and PCU2.

Two loading units are available, delivering a maximum output current
of 2000A. Each loading unit has three output taps to allow for a wide
range of load impedances. Timing modes are available to test under and
over current devices, re-closers, under and over voltage devices, current
trips and circuit breakers.
