Switchgear interlocking system | Electromer

A switchgear interlocking system is a safety mechanism used in electrical power systems to prevent unsafe or unintended operations of electrical equipment. The interlocking system ensures that certain electrical equipment, such as circuit breakers or disconnect switches, are operated in a specific sequence to avoid damage to the equipment or harm to people working on the system.
Interlocking systems use mechanical or electrical devices to prevent certain operations until specific conditions are met. For example, a circuit breaker cannot be closed unless the disconnect switch is open and the bus bars are de-energized. This prevents damage to the circuit breaker and also ensures that no one is working on the equipment when it is energized.
There are many different types of interlocking systems, including mechanical locks, electrical locks, and computer-based systems. The specific type used will depend on the application and the level of safety required.
