23.2: Reactance, Inductive and Capacitive

Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum. Although a capacitor is basically an open circuit, there is an rms current in a circuit with an AC voltage applied to a capacitor. This is because the voltage is continually reversing, charging and ...

Transformer and Reactor Testing – Dielectric Tests

Induced voltage tests on shunt reactors are not strictly induced tests, but are tests made by applying a test voltage between the line terminals such that up to two times rated volage appears across the shunt reactor winding. As shunt reactors have only one winding, the test supply is normally connected via a suitable test transformer.

Surge Capacitor, Reactor and Absorber | Devices | Electrical Engineering

In this article we will discuss about the functions of surge capacitor, reactor and absorber in a power system.
