Protecting the power system

Viswanathan Krishnan discusses the current scenario with regards to the technology and market of switchgears
In the electric power industry, switchgears refer to a collection of switching devices (for example, electrical disconnects and/or circuit breakers). These play a vital role in electrical protection (for example, protection against overload currents, short circuit currents and insulation failures) and safe isolation from live parts so that the personnel can carry out the maintenance/installation work with safety. Located on both the high voltage and low voltage side of the transformer, switchgears also come handy for local or remote switching purposes such as functional switching, emergency switching, emergency stopping and switching off for mechanical maintenance....... more>>
