ELECTRICAL MAINTENANCE LOW AND MEDIUM VOLTAGE

Deskripsi ELECTRICAL MAINTENANCE LOW AND MEDIUM VOLTAGE

The backbone of many electric power systems is the medium voltage distribution system. Typically operating at voltages ranging from 2,400 to 34,500 Volts, voltage stress, corona, surges and protection of equipment all create unique challenges in design, equipment selection, operation and engineering. This 2 day class takes you through the basics of medium voltage power systems including components,equipment, design and operation problems as well as protection of medium voltage systems.
