Faults often cause low voltages that might affect equipment operation. To perform a voltage sensitivity study, first select the One-Line Output tab of the Short Circuit Options dialog box. Select the High Voltage Remote Buses check box, the Low Voltage Remote Buses check box, or both. To open this dialog box, click Short Circuit > SC Options (toolbar menu: Tools > Short Circuit Options). Then, fault a bus on the one-line. Buses that are highlighted in red indicate voltages lower than the defined threshold limit. If you choose only High Voltage, buses under 1000 volts are not highlighted.
Note: Voltage sensitivity results are only available on the one-line after a fault operation on a single bus.
You can obtain a tabulated bus and voltage list for each fault by selecting the Voltage Sensitivity check box in the Text Output tab of the Short Circuit Options dialog box.
