Operational Notes

Description
Wiring
COM1 and COM2 of the IC694ACC200 must be connected to functional ground
(Earth ground).
COM1 and COM2 must not be connected to Neutral in a WYE power system.
In certain fault conditions, Neutral can be pulled to the full voltage of any phase. Such
a fault condition can pose a danger to personnel and damage the IC694ACC200. See
GFK-2749 for wiring diagrams.
Breaker Delay
When the ANSI 25 Breaker Delay parameter is set to a non-zero value, the phase
angle difference at which RelayCloseOK (%I offset 7) is set and the IC694ACC200
relay outputs close varies in direct proportion to the rate of change of the phase angle
of Grid 2 relative to Grid 1. Higher rates of phase angle change and larger breaker
delays require that the PSM assert RelayCloseOK earlier, to ensure that the breaker
contacts close within the safe region set by the ANSI 25 Phase Shift Threshold
parameter
Delta Power Configurations
Phase-to-Neutral voltages are not reported in Delta power configurations because
there is no Neutral reference.
Nominal Voltage
Nominal Voltage refers to the:
Phase-to-Neutral RMS voltage in a WYE power system.
Phase-to-Phase RMS voltage in a Delta power system.
Nominal Current
Setting a negative Nominal Current value implies that the IC694ACC200 grid inputs
are connected to a load (drawing power), rather than a power source (producing
power). The power and energy values will be reported as negative numbers. The CTs
must be wired with the correct polarity to achieve the negative power and energy
values. RMS current is necessarily reported as a positive number, due to the RMS
calculations.
