Capacitors, Inductors, and Transformers | Electrical A2Z

Capacitors. A capacitor is an electrical device that stores energy in the form of an electric field established by an electrical charge its most basic form, the capacitor is constructed of two conductive plates placed physically in parallel and separated by an insulating material called the dielectric. Connecting leads are attached to the parallel plates.

Defining Size and Location of Capacitor in Electrical System (2)

The most accurate method of selecting a capacitor is to take the no load current of the motor, and multiply by 0.90 (90%). Example: Size a capacitor for a 100HP, 460V 3-phase motor which has a full load current of 124 amps and a no-load current of 37 amps. Size of Capacitor = No load amps (37 Amp) X 90% = 33 Kvar.

Capacitive Voltage Transformers (CVT)

As the CVT is connected between the line and earth, therefore phase voltage (400/1.732 = 230 kV) will be applied. Therefore, Voltage across the Capacitor C 1 = (230×C 2)/(C 1 +C 2). Voltage across the Capacitor C 2 = (230×C 1)/(C 1 +C 2). Thus if an Electromagnetic Unit is connected across the C2 then its voltage rating will reduce.
