Circuit Source

A circuit (feeder) is the aggregate of the conductors and equipment downstream of a substation breaker or recloser. CircuitSource stores attributes that describe characteristics of the circuit measured or estimated at the breaker or recloser. These attributes include capacity, measured in kilowatts (kW); resistance, measured in ohms; and load, measured in reactive kilovolt-amperes (kVAR).

Associations: BusBar, CircuitBreaker, Recloser

Subtypes: kW, Swing, Voltage Controlled. The use of subtypes is optional. The Subtype attribute can be removed if subtypes aren't used in the model.

Model Names: CIRCUITSOURCE
