1 DESCRIPTION OF EQUIPMENT
The PCU2 is a primary current injection system designed to be used in conjunction with a T&R
Test Equipment loading transformer. Depending on the loading unit used, currents up to
6000A are available for 5 minutes and 12kA for 1 second.
Accurate true rms metering facilities and a flexible timing system are provided.
WARNING
The PCU2 and associated loading units are designed to be use
d on ‘dead’ systems (i.e.
no externally supplied voltages are present on the test object). Under no
circumstances connect the PCU2 or loading unit to a live system. Always check that
the power to the device under test is off and the circuit is isolated and grounded before
making any connections.
