About Photovoltaic Energy StorageAs 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.
