They are used to protect the line. Protection is made with current transformer, relay, and circuit breaker . When the circuit breaker is on the set of values ??gives the opening or closing command.
Contents:
Busbar: copper units of equipment that can connect to each other.
Earthing switch: Provides connection between soil electrical circuits that are not under tension. It is air insulated.
Circuit breaker: including short-circuit the circuit element is capable of opening and closing under load. Task to cut off load. It protects against the circuit. Three polarity. Circuit breaker, circuit breaker that built on his wheel.
Current Transformer: reduces the current which pass through the busbar to the desired value as the current measurement or protection purposes. Epoxy resin is used as a set point or LPCT. Ends are left closed.
Relay: Energy ,that is on the busbar, is converted into an analog or digital signal measurement devices and related mechanisms of human-machine interfaces based on vector values ??are used in order to run.
Voltage indicators: a cell indicating whether the capacitive voltage cable connection at the power indicator light panel, the front face of the cell.
Heater: air drying and prevents formation of moisture.
