5.4.8.3 NEUTRAL OVERVOLTAGE ELEMENT (HIGH LEVEL AND LOW LEVEL) (59NH/59NL)
The Neutral Overvoltage element can be used to detect an asymmetrical system voltage condition due to a ground fault or
to the loss of one or two phases of the source.
The element responds to the system neutral voltage (3V0), calculated from the phase voltages or measured by the 4th
voltage transformer.
VT errors and normal voltage unbalance must be considered when setting this element.
The element time delay is selectable between 0 and 900 seconds and incorporates a reset with a selectable delay between
0 and 900 seconds.
Notice that the neutral overvoltage element will not be available if a
DELTA
Connection is set in the
Phase VT Connection
setting in General settings, and the fourth voltage transformer input is set to the busbar voltage (Vx in
Auxiliary Voltage
setting). This is because with this combination of settings it is not possible to calculate the zero sequence component from
the phase-to-phase voltage magnitudes.

The snapshot event setting enables or disables the snapshot event generation for this element.
5.4.8.4 AUXILIARY OVERVOLTAGE ELEMENT (59X)
This is an Auxiliary overvoltage element for general use that uses as its input magnitude the voltage measured by the 4
th
VT. The time delay for element 59X can be set from 0 to 900 seconds. The element has a reset than can be programmed
from 0 to 900 seconds.

The snapshot event setting enables or disables the snapshot event generation for this element.
