Description

The PCU1-SP Mk2 Primary Current Injection Test System, a medium powered instrument, enables output currents of up to 5000A (11.5kVA for 40 seconds). It comprises a separate control unit that houses all metering and control functions, along with a loading unit (such as the NLU200, NLU2000, or NLU5000) responsible for delivering the high current output.

The PCU1-SP Mk2 Primary Current Injection Test System is a medium-powered instrument that can deliver output currents of up to 5000A (11.5kVA for 40 seconds). It consists of a control unit and a loading unit (NLU200, NLU2000, or NLU5000) that delivers the high current output.

This system is perfect for primary current injection, stability testing, and circuit breaker testing, and also offers direct-reading CT ratio and polarity tests. It comes with a 100A secondary injection output and 3 loading units that provide maximum output currents of 2000A or 5000A. Each loading unit, except NLU200, has three output taps to accommodate a wide range of load impedances.

The control unit has an 11.5kVA rating and can handle 2-second overload capabilities of up to 23kVA using pulse mode. All metering functions are digital and accurate, with a memory feature that retains the current reading even when the output trips or is switched off. The system uses a reliable solid-state device to control the current, which automatically shuts off when the device under test experiences a trip event.

The PCU1-SP Mk2 also has a high-accuracy timing system that allows for precise timing tests with a resolution of 1ms. It offers automatic selection for normally open or normally closed contacts, with the status of the contacts displayed on the front panel. It provides various timing modes for testing under and over current devices, re-closers, under and over voltage devices, current trips, and circuit breakers.

To ensure optimal performance and compatibility, a comprehensive range of high current output leads is available in different lengths. Output leads designed for use with the NLU2000 are available in lengths ranging from 1.5m to 5m, while leads suitable for the NLU5000 come in 1.5m and 3m variants.

5 reviews for PCU1-SP MK2 Primary Current Injection Test System

  1. Ahmed Ali

    T&R recommended the shortest output leads before buying and proved to be right. This test system works as advertised and enables me to do my work safely. Thank you T&R!

  2. Robert Jones

    Rented one of these kits from Sunbelt Rentals for some work in a substation requiring 4000A. Proved to be exactly what I needed, worth every penny and went on my list of instruments for future purchases.

  3. Sebastián Fernández

    We got a full set including output leads and a trolley and we couldn’t be happier. Apart from some dirt, there is no sign of damage. The trolley really helps moving the system around.

  4. Michael Davis

    We have been using PCU-SP Mk2 kit with confidence for more than 6 years. Being able to do secondary current injection as well has proven to be very helpful.

  5. Priya Patel

    Loading Units are not interchangeable, apart from that the 2 sets we own have proven their value and fit for our purposes.
