Considerations for capacitance-current switching applications include maximum voltage for application, frequency, capacitance current, interrupting time, transient overvoltage, open-wire transmission lines, capacitor banks, cables, switching through transformers, unusual circuits, effect of load, effect of reclosing, resistor thermal limitations, and the current pause method. Capacitance currents and recovery voltages under fault conditions are also addressed. 517 $aANSI/IEEE C37.012-1979: IEEE Application Guide for Capacitance Current Switching for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis 606 $aElectric circuit-breakers$xStandards 606 $aElectric circuits$xAlternating current$xStandards 606 $aElectric capacity 615 0$aElectric circuit-breakers$xStandards. 615 0$aElectric circuits$xAlternating current$xStandards. 615 0$aElectric capacity. 676 $a338.47621312 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279877903316 996 $aANSI$92072434 997 $aUNISA
