Three high-impedance differential protection instances are offered. By default,
HIAPDIF1 is for phase A current channel, HIBPDIF1 is for phase B current channel,
and HICPDIF1 is for phase C current channel. The
ALARM
outputs of the phase-
segregated current transformer supervision HZCCxSPVC block HIxPDIF.
HIAPDIF1 operate signal is connected to LED 1, HIBPDIF1 operate signal is
connected to LED 2, HICPDIF1 operate signal is connected to LED 3. All the start
signals from HIAPDIF1, HIBPDIF1 and HICPDIF1 are connected to LED 4.

Phase segregated CT supervision
Three phase-segregated current transformer supervision instances are offered. By
default, HZCCASPVC1 is for phase A current channel, HZCCBSPVC1 is for phase
B current channel, and HZCCCSPVC1 is for phase C current channel.
All the
ALARM
output signals are connected to LED 5.
