Switchgear [5] includes the power switching components, e.g., the main disconnecting device, and breakers protecting the supply conductors and the branch circuits in the machine. Controlgear [ 6 ] includes all of the control system components downstream of the switchgear, out to the final point of control, but not including the machine actuators.
The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions.
Tram switchgear This circuit breaker uses both SF 6 and air as insulation. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults ...
