Compensation of reactive energy absorbed by the transformer
The reactive power absorbed by a transformer cannot be neglected, and can amount to (about) 5% of the transformer rating when supplying its full load. Compensation can be provided by a bank of capacitors. In transformers, reactive power is absorbed by both shunt (magnetizing) and series (leakage flux) reactances.

6 FAQs about [Reactive power compensation capacitor test items]
What is reactive power compensation?
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
Why is capacitive shunt compensation important?
Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.
What happens if a capacitor peaks 3 times rated voltage?
In low voltage networks, inadmissibly high voltage peaks of up to 3 times the rated voltage can occur through switching operations. If these loads lead to flashovers in the dielectric, the self-restoring efect is triggered. The capacitor remains fully functional as this happens.
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.
What is the difference between inductive and capacitive reactance?
The inductive and capacitive reactances are frequency dependent (hence are only present in AC systems), oppose each other and are at right angles to the pure (DC) resistance. The net reactance, which is usually inductive, opposes the flow of current, and the power required to overcome this reactance is called reactive power (Q).
What is a reactive power device?
When reactive power devices, whether capacitive or inductive, are purposefully added to a power network in order to produce a specific outcome, this is referred to as compensation. It’s as simple as that. This could involve greater transmission capacity, enhanced stability performance, and enhanced voltage profiles as well as improved power factor.
