Measure the voltage on the line with voltage transformers.
Content:
Busbar: copper units of equipment that can connect to each other.
Earthing switch: Provides connection between soil electrical circuits that are not under tension.
Air insulated voltage transformer: reduces the voltage, that pass through the busbar to the desired value as the measurement or protection purposes. It is epoxy resin.
Heater: air drying and prevents formation of moisture.
Fuse : is used for protection
