SUMMARY
The discussion clarifies the distinction between BIL (Basic Insulation Level) rating and maximum continuous voltage for electrical equipment. BIL represents the highest voltage the equipment can withstand for a short duration, while the maximum continuous voltage, often referred to as working voltage (VW), indicates the voltage the equipment can handle during regular operation. For a capacitor bank rated at 115kV, operating at 1.1 per unit (pu) could potentially lead to damage if the continuous voltage exceeds the specified VW.
PREREQUISITES
