Figure 9.27 (a) Circuit configuration to illustrate secondary resonance, (b) overvoltages on switching depending on coupled circuit parameters.

The switched capacitor can be on in the utility system while the secondary capacitor in service can be at a user's electrical system. This overvoltage can cause damage to the secondary capacitors, result in nuisance tripping of ASDs, and damage to the sensitive equipment.

The maximum switching surges can be expected if

9.65

The angular frequencies of the circuit are

9.66

where

9.67

The voltage across capacitor is

9.68

And the maximum voltage is

9.69
