T&R Test Equipment is a market leader in the field of current injection
equipment. The range includes secondary injection units with 50 Amp
output capability up to 6000 Amps primary injection systems. All have
true RMS metering, a flexible timing system, and an easy to understand
The 50A-3PH is a three-phase injection system providing commissioning
and maintenance engineers with a flexible system for testing protective
systems. It has an easy to understand panel layout and a simple user
interface. The status of every function can be seen at a glance, and
there are no complex menus to navigate.
An auxiliary metering input is provided and can measure voltage,
current, frequency, and the phase between any of the current outputs and
an external voltage or current.
The timing system is very flexible without compromising ease of use,
allowing trip times, reset times and closure times to be quickly
measured to a high degree of accuracy. Two independently isolated
contact inputs are provided, and the timing system may also be used as a
