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.
IEC 61636 Software interface for Maintenance Information Collection and Analysis (SIMICA) IEC TR 61641 Enclosed low-voltage switchgear and controlgear assemblies – Guide for testing under conditions of arcing due to internal fault; IEC 61642 Industrial a.c. networks affected by harmonics – Application of filters and shunt capacitors
Preventive maintenance checks and services (PMCS) in the United States Army or preventive maintenance inspections (PMI) in the United States Air Force are the checks, services, and maintenance performed before, during, and after any type of movement or before the use of all types of military equipment.
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 ...
750 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.
The construction features of an electrical room vary depending on the scope of the equipment to be installed. Floors may be reinforced to support heavy transformers and switchgear. Walls and ceilings may have to support a heavy cable tray system or busbars. Additional ventilation or air conditioning may be needed, since electrical apparatus ...
The company's products include overhead electrical line and other outdoor switchgear for voltages up to 38 kV, indoor switchgear for voltages to 15 kV, containerised electrical substations, HV DC switchgear for currents up to 12 kA with voltages up to 1.8 kV and protection relays, as well as servicing, maintenance and repair services.
Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.
