IAG   7014 / 7034

High impedance differential protection

The IAG 7014 and IAG 7034 relays provide high speed protection which is stable and, at the same time sensitive, at a cost considerably lower than biased differential protection.
The IAG 7014 and IAG 7034 relays may be used in the following circumstances:

  • Instantaneous longitudinal differential protection of bus-bars and eventually alternators, synchronous or induction machines (IAG 7034).
  • Instantaneous restricted earth fault protection of bus-bars or transformers (IAG 7014).
  • Instantaneous transverse protection of machines with two windings in parallel.

Their modular draw-out case, type R, may be mounted either as a separate relay, flush or projection mounting, or as an alement in a standard 19" rack cradle.
