T&R 100ADM-F Current Filter Unit
Includes: The 100ADM Filter Unit is supplied in an insulated case complete with protective cover and carrying strap.
The T&R 100ADM-F 100A waveform filter unit reduces the level of current harmonics when testing electro-mechanical protection relays. It is designed for use with the T&R 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.
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.
