Medium Voltage Power Systems – 16 Hours

Medium Voltage Training

16 Hours | 16 PDHs | 1.6 CEUs

The backbone of many electric power systems is the medium voltage distribution system. What is medium voltage? It is typically voltages ranging from 2,400 to 34,500 Volts. This medium voltage training addresses voltage stress, surge arrestors, protection of equipment, insulation voltage classes, insulation coordination, equipment selection, operation and more.

$995.00
