Voltage Regulator Unit

Voltage regulators provide voltage control where feeders of different lengths and diverse load conditions are supplied from the same substation bus.

Designer uses the DESIGNUNIT model name on this class to designate it as an electric device unit object class. The Designer Work Function Tool uses this model name to identify all electric device unit object classes.
