2. High-voltage interface relay - Wikipedia

   en.wikipedia.org/wiki/High-voltage_interface_relay

   High voltage interface relays, a.k.a., interface relays: [1] [2] or coupling relays or insulating interfaces [3] [4] is a special class of electrical relays designed to provide informational and electrical compatibility between functional components isolated from each other and not allowing for a direct connection due to a high difference of potentials.

   IEC 60644 Specification for high-voltage fuse-links for motor circuit applications; IEC 60645 Electroacoustics – Audiometric equipment; IEC 60648 Method of test for coefficients of friction of plastic film and sheeting for use as electrical insulation; IEC 60651 Sound level meters (Withdrawn, replaced by IEC 61672-1:2002 and IEC 61672-2:2003)

4. High-voltage switchgear - Wikipedia

   en.wikipedia.org/wiki/High-voltage_switchgear

   800 kV high-voltage switchgear. High-voltage switchgear is any switchgear used to connect or disconnect a part of a high-voltage power system.This equipment is essential for the protection and safe operation, without interruption, of a high voltage power system, and is important because it is directly linked to the quality of the electricity supply.

5. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Modern automatic circuit reclosers are significantly more advanced than the original hydraulic units. The advent of semiconductor based electronic protective relays in the 1980s resulted in increased recloser sophistication, allowing for differing responses to the various cases of abnormal operation or fault on an electric power distribution ...

6. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Current and voltage transformers to step down the high voltages and currents of the electrical power system to convenient levels for the relays to deal with; Protective relays to sense the fault and initiate a trip, or disconnection, order; Circuit breakers or RCDs to open/close the system based on relay and autorecloser commands

7. Hybrid switchgear module - Wikipedia

   en.wikipedia.org/wiki/Hybrid_switchgear_module

   High-voltage switchgears have been traditionally distinguished according to the medium used to extinguish the arc. In the case of the hybrid switchgear modules, this device developed during last 90’s uses two different types of technologies: one to extinguish the arc and the other to connect to the other equipment of the high voltage substation, for pursuing the goal of maximizing the ...
