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.
