Medium Voltage Power Systems

Register 3 People and the 4th is FREE!

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 by Jim Phillips, P.E. takes you through the fundamentals of medium voltage power systems including the components, equipment, design and operation problems as well as overcurrent protection, surge protection, insulation coordination and many other important aspects of medium voltage power systems.

One of the many topics that Jim discusses in this 2 day class is overcurrent relays beginning with the electro-mechanical relay and moving through digital relays and relay settings.  This class also includes many other topics such as surge protection, insulation coordination and more.   See Jim’s video below.
