Details

The 100ADM-F filter unit reduces the level of current harmonics when testing electro-mechanical protection relays.

It is designed for use with our range of secondary injection test sets. All electromechanical protection relays have iron cores that saturate and distort the test current under high overload test conditions. This distortion causes significant errors in the measured trip time of these relays during testing. Distortion of the waveform can be a particular problem with disc induction type over-current and sensitive earth fault relays.

T&R 100ADM-F Current Filter Unit features:

  • Forces test current to a sinusoid
  • Greatly improves timing accuracy when testing
  • electromechanical relays
  • Wide range of test currents
  • High overload capability
  • 50/60Hz operating frequency
  • High efficiency
  • Current monitoring output
  • Compact and portable

The 100ADM-F has nine current ranges covering 0.25A to 100A and is supplied in an insulated case complete with protective cover and carrying strap.
