What is a high voltage capacitor bank?

High voltage capacitor banks are composed of elementary capacitors, generally connected in several serial-parallel groups, providing the required electrical characteristics for the device.

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.

How shunt capacitor banks affect power system performance?

Located in relevant places such as in the vicinity of load centers the use of SCBs has beneficial effect on power system performance: increased power factor, reduced losses, improved system capacity and better voltage level at load points. Shunt capacitor banks are protected against faults that are due to imposed external or internal conditions.

What is the minimum number of capacitor units connected in parallel?

As a general rule, the minimum number of units connected in parallel is such that isolation of one capacitor unit in a group should not cause a voltage unbalance sufficient to place more than 110% of rated voltage on the remaining capacitors of the group.

What are Lv capacitor banks?

Composition of LV capacitor banks A distinction is made between fixed value capacitor banks and “step” (or automatic) capacitor banks which have an adjustment system that adapts the compensation to the variations in consumption of the installation.

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.
