3.2.7 RESTRICTED EARTH FAULT INPUTS
Restricted Earth Fault protection is often applied to transformers having grounded wye windings to provide
sensitive ground fault detection for faults near the transformer neutral. The Sensitive Ground input (terminals
G3, H3) can be used.
Although the 750/760 is designed for feeder protection, it can provide Restricted Earth Fault protec-
tion on transformers that do not have dedicated protection. To use the 750/760 for this type of protec-
tion, a stabilizing resistor and possibly a non-linear resistor will be required. For more details see
Section 12.5.6: RESTRICTED EARTH FAULT on page 12–37.
