What is the switching operation?

Electrical equipment under the jurisdiction of an electrician can be divided into four different states of use: operation, hot standby (referring to line charging without load), cold standby (referring to line power failure can be sent at any time), overhaul. In order to switch these electrical devices from one state of use to another, a series of operations are required, which is called a trip operation.

The switching operation mainly refers to pulling or closing some circuit breakers and disconnectors. But it also includes the removal and installation of temporary grounding wires.

The power system is an indivisible whole, and the state of the local device changes, which must affect other parts of the system. Therefore, various switching operations must be carried out seriously.

Switching operation is a complicated and important task. In the event of a misoperation, electrical equipment may be powered off or damaged, endangering personal safety.
