6 Frequently Asked Questions about “Replacement period of compensation capacitor”
What is a capacitor bank?
The capacitor bank is connected to the main distribution board and provides compensation for the whole installation. It remains in operation permanently, at least during the reactive energy billing period for normal operation of the site. This can combine the advantages of high voltage global compensation with low voltage sector compensation.
When are series capacitors effective?
Series capacitors are very effective when the total line reactance is high. Series capacitors are effective to compensate for voltage drop and voltage fluctuations. Series capacitors are of little value when the reactive power requirements of the load are small.
Can a capacitor bank be used for low power compensation?
The capacitor bank is connected upstream of the HV/lV transformer. The additional cost connected with high voltage insulation rules out any benefit of using this for low power compensation (apart from in the case of individual requirements).
When are series capacitors of little value?
Series capacitors are of little value when the reactive power requirements of the load are small. In cases where thermal considerations limit the line current, series capacitors are of little value since the reduction in line current associated with them is relatively small.
How do you compensate a motor terminal with a capacitor?
compensation at the motor terminals will however remain possible by inserting a contactor (c2), controlled by an auxiliary contact of the motor contactor (c1), in series with the capacitor. 3. Reactive compensation of transformers
What if the capacitor power required to compensate a motor is greater?
If the capacitor power required to compensate the motor is greater than the values given in the previous table or if, more generally: compensation at the motor terminals will however remain possible by inserting a contactor (c2), controlled by an auxiliary contact of the motor contactor (c1), in series with the capacitor.
