EquivalentBranch

Class Description

The class represents equivalent branches. In cases where a transformer phase shift is modelled and the EquivalentBranch is spanning the same nodes, the impedance quantities for the EquivalentBranch shall consider the needed phase shift.

Attributes

Name Type Description
negativeX12 Reactance Negative sequence series reactance from terminal sequence 1 to terminal sequence 2. Used for short circuit data exchange according to IEC 60909.
Usage : EquivalentBranch is a result of network reduction prior to the data exchange.
