The height of the building is not a creiteria for
installing of lightning arrester. If this is the only
building in the area then we have to install the lightning
arrester. But generally it should be installed on the
highest building or tower in the immediate vicinity.

It consists of spikes which can be installed on the
perifery of the building at distances of about 15 to 20
feet.

testing of protective relays will be discussed later.

In the UVR(Under Voltage Relay) there is a knob for the hysteresis setting. what is this setting? its threshold is given from 5% to 50%. please help me....
