59G Ground Overvoltage
NOTE:
Two or Four voltage inputs are available
for the M-3311A. The voltage input can
be a phase voltage input or voltage
generated from a broken delta VT
connection. 81O/U, 27, and 24 Functions
are only available if the voltage input
is connected to the phase voltage.
If the voltage input is connected to
phase voltage, Function 59G will be
unavailable.
Function 59G is only available if the voltage input
is connected to a broken delta VT. If voltage input
is connected to broken delta VT, Functions 81O/U,
27, and 24 will be unavailable.
The 59G Ground Overvoltage function provides
protection for ground faults on the system.
Pickup setting for 59G should be set in such a way
that it is higher than normal neutral voltage during
unbalanced conditions. The time delay should be
set to coordinate with downstream ground relaying.
NOTE:
The above screens are for Four Winding applications,
for two and three winding applications the screens for
element number 3 are the same.
