High Impedance Differential IAG7014 / 7034
The IAG7014 and 7034 are high-impedance differential overcurrent relays designed to provide stability during through-faults. They have different functions:
IAG7014: Instantaneous single-phase differential overcurrent or restricted earth fault protection of bus-bars or transformers.
ANSI functions: 87B or 87T or 87REF
IAG7034: Three phase, instantaneous longitudinal differential protection of bus-bars and alternators, synchronous or induction machines or instantaneous transverse protection of machines with two windings in parallel.
ANSI function: 87
