Fault([BRANCH nearbusnum farbusnum ckt], faultlocation, faulttype, R, X]);<br />

Call this function to calculate the fault currents for a fault. If the fault element is a bus then do not<br />

specify the fault location parameter. If the fault element is a branch, then the fault location is<br />

required.<br />

[Bus num]: This specifies the bus at which the fault occurs. You may also specify the bus using<br />

secondary keys or labels:<br />

[BUS "name_nomkv"]<br />

[BUS "label"]<br />

[BRANCH nearbusnum farbusnum ckt]: This specifies the branch on which the fault occurs.<br />

You may also specify the branch using secondary keys or labels:<br />

[BRANCH "name_kv1" "name_kv2" ckt]<br />

[BRANCH "buslabel1" "buslabel2" ckt]<br />

[BRANCH "label"]<br />

Fault location: This specifies the percentage distance along the branch where the fault occurs.<br />

This percent varies from 0 (meaning at the nearbus) to 100 (meaning at the far bus)<br />

Faulttype: This specified the type of fault which occurs. There are four options:<br />

SLG: Single Line To Ground fault<br />

LL: Line to Line Fault<br />

3PB: Three Phase Balanced Fault<br />

DLG: Double Line to Group Fault.<br />

R, X: These parameters are optional and specify the fault impedance. If none are specified, then<br />

a fault impedance of zero is assumed.<br />
