What should a capacitor bank have?

The capacitor bank should has two technical drawings, namely, main circuit diagram and control circuit diagram. The main circuit diagram should provide information how to connect the capacitor bank to the supplying switchgear: There is three phase network incoming to supply the capacitor bank (Low Voltage switchgear).

How a capacitor bank is developed?

Capacitor banks are developed to generate the pulse current. Switching circuit consisting of Double Pole Double Throw (DPDT) switches, thyristor, and triggering circuit is developed and tested. The coil current is measured using a Hall-effect current sensor. The magnetic pulse generated is mea-sured and tabulated in a graph.

What happens if a capacitor bank is unbalanced?

An unbalance in the capacitor bank will cause an unbalance in the voltages at the tap point of the three phases. The protection scheme consists of voltage sensing device connected between the capacitor intermediate point and ground on each phase. A time delay voltage relay with third harmonic filter is connected to the broken delta secondaries.

What happens if a capacitor bank is removed?

The capacitor bank may be subjected to overvoltages resulting from abnormal system operating conditions. If the system voltage exceeds the capacitor capability the bank should be removed from service. The removal of the capacitor bank lowers the voltage in the vicinity of the bank reducing the overvoltage on other system equipment.

What determines the position of new capacitor banks?

The value of the kVAR connected to kVA per feeder, the position on the feeder of existing capacitor banks, and any concentration of present or future load are all considered in determining the position of the new capacitor banks.

What is the detuning factor of a capacitor bank?

Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.
