T&R Test Equipment is in the field of current injection equipment.

The range includes secondary injection units with 100A 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 200ADM is the new addition to the range and provides commissioning and maintenance engineers with a flexible system for testing protective systems.

The 200ADM 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 back-lit display on the 200ADM is bright and clear with a wide viewing angle.

An auxiliary metering input is provided and can measure AC and DC voltage, current, frequency and the phase between the main current output and an external voltage or current.

A stabilised DC supply is provided to power the relay under test, along with an independently variable AC output.

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.

The unit has a range of outputs allowing injection of currents as low as 1mA and as high as 200A. Voltages up to 240V are available on the main outputs, allowing high impedance current relays and voltage relays to be tested.

Four 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 200ADM is comprehensively protected by overcurrent, duty cycle and thermal trips and keeps the user fully informed of any trip condition. The 200ADM can be used to test many types of single phase secondary protection including:

  • Over and under current relays
  • IDMT relays
  • Over and under voltage relays
  • Auto-reclosers
  • Time delay relays
  • Earth fault relays
  • Miniature circuit breakers
  • Power relays
  • Tripping relays
  • Thermal relays
  • Voltage regulating relays

200ADM current injection system is available from Macey's Electrical .
