The Basics of Switching Devices In Medium Voltage Switchgear

Medium Voltage EquipmentBasics of Switching DevicesWhat Can The Different Switching Devices do?Apart from the public supply, there are still other voltages fulfilling the needs of consumers in industrial plants with medium voltage systems; in most cases, the operating voltages of the motors installed are decisive. Operating voltages between 3kV and 15kV are frequently found in industrial supply systems. In power supply and distribution systems, medium voltage equipment is available in: 1. Power stations, for generators and station supply systems. 2. Transformer substationsof the primary distribution level (public supply system or systems of large industrial companies), in which power supplied from the high voltage system is transformed to medium voltage. 3. Local supply, transformer or customer transfer substations for large consumers (secondary distribution level), in which the power is transformed from medium to low voltage and distributed to the consumer.Get price
