Answer / iamdon

Nominal voltage is the rated voltage of any device/system.

Answer / sudhi

voltage for which the device is intended to be used.
The nominal voltage must be lower than the rated voltage, so there is a satisfactory margin of safety.
For example, in the 11 kV voltage class(rated voltage), a Nominal System Voltage may be 10.8 kV, or 9.57 kV, or other.

Answer / viral shah

electrical devices are designed to work with one nominal voltage, which represents a band of possible actual voltages, power factor and AC waveform shapes.
A solar panel designed to charge a "12 V lead–acid battery" will often be called a "12 volt panel", even though the actual voltage while charging (of both the panel and the battery) is around 14 V, and the open-circuit voltage of the solar panel is around 17 V.

An 11kv system consisting of an underground cable to a sub station about 300 meters away was shut down for about 10 hrs. On energising, it tripped off on earth fault about 10---20 mins later 6 times but since than it is not tripping.its already 3 weeks now. The SPAJ was found to be fine. what could be the cause.No test had been done to determine the cause of the trippings till now because of demand.
