What is the compensation capacitor
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Compensation for power factor means adding some capacitive reactance to compensate for the usual inductive reactance. Fixed capacitors means that you may have to pick certain discrete values so you can decide to leave the load as somewhat inductive (undercompensated) or capacitive (overcompensated). ...
