Power capacitors are very beneficial in power networks. They provide reactive power required by motors, transformers, etc. This increases the transmission capacity and reduces losses thanks to higher power factors. They enable the power factor targets of the utilities to be met. Power capacitors and series reactors are also a key component in various filter solutions that reduce harmonic cont...
