Single stage and multi-stage capacitor banks are equipped with various switching devices that reliably energize and de-energize shunt power capacitors. These switching devices are often combined with the key interlock, protection, and control systems to allow for a fully integrated power capacitor bank.
The phase shift of the switched capacitor inverting amplifier has an excess linear phase delay. When the frequency is equal to 0.5f c, this delay is 90°. One must be careful when using switched capacitor circuits in a feedback loop because of the excess phase delay.
Switched capacitor circuits are not new. James Clerk Maxwell used switches and a capacitor to measure the equivalent resistance of a galvanometer in the 1860’s. Figure 9.1-1 (a.) Parallel switched capacitor equivalent resistor. (b.) Continuous time resistor of value R.
Interrupter portion of switch does not provide a visible open gap; therefore, it cannot be used to establish a safety clearance for personnel. In back-to-back capacitor bank switching applications, it is recommended that inrush current be limited to the values shown for maximum maintenance-free performance.
These switching devices are often combined with the key interlock, protection, and control systems to allow for a fully integrated power capacitor bank. Switching devices include circuit breakers (fixed and drawout), vacuum contactors, and capacitor switches. For transient free switching, NEPSI recommends the Southern States CapSwitcher.
