SAP - SWITCHGEAR AND PROTECTION 22524 Manual #SAP
What is Switchgear?
Electrical Switchgear is connected to electric supply systems and is used in both low and high voltage power transformers. Its purpose is to de-energise set up for maintenance and repair to correct the faulty issues. Every time there is a defect in the power system, like a short circuit, a massive current flows through the electric setup, which is damaging to the structure and also causes supply disruption to the users. It is crucial to ensure optimum electrical protection.
How Do Switchgear Work?
Automated protective switchgear consists of a relay and circuit breaker. The relay acts whenever there is a fault. The relay closes the faulty circuit and disconnects the disrupted line. This ensures that the appliances do not get damaged and there is an uninterrupted supply of power. Relays provide that the faulty part remains isolated while the healthy part continues to function as usual.
Features of Switchgear
- Boosts Reliability
Switchgear ensures undisturbed interconnectivity and a higher capacity of generating stations. It enhances reliability. This implies that the switchgear separates faulty sections of the circuit in the case of malfunction.
- Swift response
In the case of a malfunction in the circuit, the switchgear counters quickly to prevent the damage from spreading into the healthy parts. Thus, It helps in preventing a complete shutdown of the circuit.
- Physical Control Facility
Switchgears also have the facility to offer hand-held operations in case of a fault of electrical control.
- Absolute Differentiation
Switchgear can alter between functioning and nonfunctioning parts in a circuit. Basis this, the switchgear then separates the non functioning components to ensure an uncompromised power supply.
