  • Recloser - Wikipedia

    In electric power distribution, automatic circuit reclosers are a class of switchgear which is designed for use on overhead electricity distribution networks to detect and interrupt momentary faults. Also known as reclosers or autoreclosers, ACRs are essentially high voltage rated circuit breakers with integrated current and voltage sensors and a protection relay, optimized for use as an overhead network

  • CHAPTER 2 HIGH VOLTAGE SWITCHGEAR - Blogger

    Switchgear is used on both high-voltage and low-voltage systems. It is required to enable generators, feeders, transformers and motors to be connected to and disconnected from the high-voltage or low-voltage system. This switching is necessary both for normal operational purposes and for the rapid disconnection of any circuit that becomes faulty.

    Production. The common static electric sparks seen under low-humidity conditions always involve voltage well above 700 V. For example, sparks to car doors in winter can involve voltages as high as 20,000 V. Electrostatic generators such as Van de Graaff generators and Wimshurst machines can produce voltages approaching one million volts, but typically produce low currents.

  • Vacuum interrupter - Wikipedia

    In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished. Vacuum interrupters are widely used in utility power transmission systems, power
