  2. Disconnector - Wikipedia

    en.wikipedia.org/wiki/Disconnector

    In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.

  3. Switchgear - Wikipedia

    en.wikipedia.org/wiki/Switchgear

    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

  5. Earth-leakage circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Earth-leakage_circuit_breaker

    An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

  7. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A Siemens air circuit breaker rated for 1000 V and 2500 A continuous current mounted on a motor control cubicle. Medium-voltage circuit breakers rated between 1 and 72 kV may be assembled into metal-enclosed switchgear line-ups for indoor use or may be individual components installed outdoors in a substation.

  8. Network isolator - Wikipedia

    en.wikipedia.org/wiki/Network_isolator

    The network isolator is a passive device, and functions without any requirement of an external power supply. A functional equivalent to network isolators is Ethernet over a small stretch of optical fibre, using media converters or Ethernet switches/network cards with fiber connections on each end.

  9. Galvanic isolation - Wikipedia

    en.wikipedia.org/wiki/Galvanic_isolation

    Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no direct conduction path is permitted. [ 1 ] [ 2 ] Energy or information can still be exchanged between the sections by other means, such as capacitive , inductive , radiative , optical , acoustic , or mechanical coupling.
