modelFaultBase
Line fault base, 3-phase dq0
Extends from Ports.Port_f (AC one port 'fault', 3-phase).
Information
The small parameter epsG is used to define voltage on the faulted line in particular when the line is disconnected from its sources. For disconnecting switches with zero 'open' conductivity, epsG can not be set to zero.
Terminology:
- lower case a, b, c: shorted phase to phase
- upper case A, B, C: shorted phase to ground
