All those transformer losses which are always constant, regardless of the load variations, are known as No-load losses. They do not vary according to the loading on a transformer. Even a small reduction in no-load …
Capacitors are the most common reactive-load compensation equipment widely utilised in power systems. The disturbance caused by capacitor switching is mainly characterised by the high-frequency oscillation generated by the interaction between the capacitor and the system inductive elements, which is generally between 200 and 1000 Hz.
