50A-3PH Current Injection System

T&R Test Equipment is a market leader in the field of current

injection equipment. The range includes secondary injection

units with 50A output capability up to 6000A primary injection

systems. All have true RMS metering, a flexible timing

system, and an easy to understand user interface.

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.

The unit has a range of outputs allowing injection of currents

as low as a few mA and as high as 50A. Voltages up to 18V

are available on the main outputs. Three true RMS metering

ranges are provided, allowing the full scale of the meter and

trip level to be set independently of the selected output.

Industry standard safety connectors are used on all inputs

and outputs for convenience, reliability and safety.

The 50A-3PH is comprehensively protected by overcurrent,

duty cycle and thermal trips, and keeps the user fully

informed of any trip condition. Auxiliary outputs and inputs

are fuse protected.

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 reclose 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 stand-alone timer.

The 50A-3ph can be used to test many types of single and

three phase secondary protection including:

• Over and under current

relays

• IDMT relays

• Auto-reclosers

• Time delay relays

• Earth fault relays

• Miniature circuit breakers

• Power relays

• Tripping relays

• Thermal relays

The back-lit display on the 50A-3PH is bright and

clear with a wide viewing angle. The results of a test

can be seen here as they appear on the display
