This component is used for generating faults on a three phase AC circuit. Line-to-line as well as line-to-neutral faults are available and fault current variable names can be specified in each phase and monitored via output channels if desired. An external connection is supplied to the component so that the user may connect any type of external fault circuit directly to the fault common point.
The Three-Phase Fault is controlled through an input signal, where the fault logic is:
0 = Cleared
1 = Faulted
The type of fault can be configured internally, or through the convenient use of an on-line dial control as shown below:
The following is a list of input control dial values that correspond to specific fault types:
0 = No Fault
1 = Phase A to Ground
2 = Phase B to Ground
3 = Phase C to Ground
4 = Phase AB to Ground
5 = Phase AC to Ground
6 = Phase BC to Ground
7 = Phase ABC to Ground
8 = Phase AB
9 = Phase AC
10 = Phase BC
11 = Phase ABC
The fault control signal can be configured automatically by using the Timed Fault Logic component, or the Sequencer components. The fault may also be controlled manually through the use of on-line controls, or through a more elaborate control scheme.
