Note

The 

SUPERVISE WITH DIGITAL INPUT

 setpoint is seen only if a digital input assigned to 

Ground Switch Status.

The neutral overvoltage function responds to fundamental frequency voltage at the 
generator neutral. It provides ground fault protection for approximately 95% of the stator 
windings. 100% protection is provided when this element is used in conjunction with the 
Neutral Undervoltage (3rd harmonic) function. The alarm element is definite time and the 
trip element can be either definite time or an inverse time curve. When the neutral voltage 
rises above the pickup level the element will begin to time out. If the time expires an alarm 
or trip will occur. The reset rate is a linear reset time from the threshold of trip. The alarm 
and trip levels are programmable in terms of Neutral VT secondary voltage.

The formula for the curve is:
