The switchgear equipment is fundamentally preoccupied with interrupting and switching currents either under normal or abnormal operative conditions.
The tumbler switch with mediocre fuse is the easiest form of switchgear and is utilized to control and assist lights and other equipment of offices and homes.
For circuits of high rating, an advanced-rupturing capacity (H.R.C.) fuse in conjunction with a switch that may suffice the goal of protecting and controlling the circuit. Nevertheless, such a switchgear cannot be utilized productively on advanced voltage method (33 kV) for two accounts.
1. When a fuse blows, it proceeds sometime to renew it and accordingly there is a disruption of service to the clients.
2. The fuse cannot successfully disrupt large fault currents, which issue from the breaks on high voltage system.
With the procession of power system, lines and other instruments are operated at high voltages and support large currents. When a short circuit fall out on the system, heavy current flowing through the equipment may reason in hefty damage. In order to disrupt such massive fault currents, machine-controlled circuit breakers (or just circuit breakers) are effectively used.
A Circuit Breaker is a switchgear that can open or close an electric circuit under normal as well as abnormal conditions. Even in cases where a fuse is competent, as regards to breaking capability, a circuit breaker may be much advantageous.
The essential properties or features of switchgear are :
Absolute reliability: With the continuing tendency of interconnectedness and the augmentative capacity of rendering stations, the demand for a dependable switchgear has become of paramount value. This is not unexpected because switchgear is inserted or added to the power system so as to amend the reliability. When fault happens on any portion of the power system, the switchgear must be operates to separate the defective section from the remainder circuit.
Perfectly certain discrimination: When fault happens on any part of the power system, the switchgear must be capable to differentiate between the inaccurate section and the high-fidelity section. It should discriminate the faulty section from the grouping without touching or making an impact on the healthy section and ensure the continuity and coherency of supply.
Speedy operation: When fault happens on any component part of the power system, the switchgear must be functioned rapidly so that no harm is done to transformers, generators and other instruments by the short-circuit currents. If break or fault is not eliminated by switchgear quickly, it is liable to spread into other healthy parts, thus threatening out-and-out shut down of the system.
Switchgear can be grouped on the ground of voltage level in to the following:
