Switchgears are as important and old as electricity generation. The first models were very primitive, all components were simply fixed to a wall. Later they were mounted on wooden panels. For reasons of fire protection, the wood was replaced by slate or marble. This led to a further improvement, because the switching and measuring devices could be attached to the front, while the wiring was on the back.

Switchgear is an important component in the electrical system charged that performs the function of carrying, making or breaking the normal current load. Switchgear are used to de-energise equipment and also to clear faults downstream. This enables reliability of the electricity supply.

There are generally different classifications associated with switchgear power systems; current rating, interrupting rating, voltage class, insulation type, interrupting device, operating method, type of current, application and purpose. Additionally, those classifications can be further broken down for added specificity. For example, a voltage classification can be further defined either as low voltage (less than 1,000 volts AC), medium voltage (1,000-35,000 voltage AC) and high voltage (more than 35,000 volts AC). By utilizing these classification and sub-classifications, equipment designers and engineers can ensure that the right equipment is utilized with different switchgear power systems.



While classification of switchgear power systems are important, it does not mean that only one classification can be used within a specific system. For example, a single line-up can combine several different types and classifications of switchgear power systems. Additionally, ratings and specifications of switchgear power systems must meet several different standards and requirements, which can include IEEE (Institute of Electrical and Electronics Engineers) and ANSI (American National Standards Institute) within North America and the IEC (International Electrotechnical Commission) standards around the world.

A switchgear has two types of components:
• Power conducting components, such as switches, circuit breakers, fuses, and lightning arrestors, that conduct or interrupt the flow of electrical power
• Control systems such as control panels, current transformers, potential transformers, protective relays, and associated circuitry, that monitor, control, and protect the power conducting components

One of the basic functions of switchgear is protection, which is interruption of short-circuit and overload fault currents while maintaining service to unaffected circuits. Switchgear also provides isolation of circuits from power supplies. Switchgear is also used to enhance system availability by allowing more than one source to feed a load.

Modern business requirements call for upgraded switchgear that ensures optimum safety, reliable power and continued business operations.
