WARNING! USE EXTREME CAUTION! Dangerously high voltages might be
present on this equipment, especially on the plate with resistors. De-energize
the primary object protected with this equipment before connecting or
disconnecting wiring or performing any maintenance. The plate with resistors
should be provided with a protective cover, mounted in a separate box or in a
locked cubicle. National law and standards shall be followed.
Connections for three-phase high impedance differential protection
GUID-C12CCAAF-5AE5-4A9C-AC9C-F56A66FD2C14 v8
Generator, reactor or busbar differential protection is a typical application for three-phase
high impedance differential protection. Typical CT connections for three-phase high
impedance differential protection scheme are shown in figure
