Switchgear refers to electrical equipment that regulates the flow of electricity within an electrical system. An automatic transfer switch provides an automated way of switching the power source from the main source to generator supply. Surge Suppressors or Surge Arrestors are very important components of switchgear and substation installations. Electrical switchgears refers to electrical devices that manages the flow of electricity within an electrical system. This means that for example the power transformer in-feed cubicle can have different primary and secondary devices from what the outgoing line feeder cubicle has. If the fault is not cleared quickly, it is likely to spread into healthy parts, thus endangering complete shut down of the system. Some types of equipment are designed to operate under both normal and abnormal conditions. In order to interrupt such heavy fault currents, automatic circuit breakers (or simply circuit breakers) are used. A brief account of these devices is given below. Electricity / By Nick Grogan. Thanks for sharing this useful information.. It can be used under full-load or no-load conditions but it cannot interrupt the fault currents. This type of equipment is directly linked to the reliability of the electricity supply. The switching device here is called a circuit breaker. Find out more about our upgrade service or get in touch today. Once the short circuit occurs within the power system, then a huge current will flow through the devices.
