Equivalent Circuit Diagram Of Potential Transformer. The induced emf e 1 is equal to the primary applied voltage v 1 less primary voltage drop. By the above two equations the transformer equivalent circuit can be drawn as shown below.
The circuit diagram of the capacitor potential transformer is shown in the figure below. Transformer equivalent circuit in phasor form in phasor form the transformer equivalent circuit takes the form shown in fig 3. In the above equivalent circuit r1 jx1 and r2 jx2 are the leakage impedances of primary and secondary windings respectively.
The stack of high voltage capacitor from the potential divider the capacitors of two sections become c 1 and c 2 and the z is the burden.
The circuit diagram of the capacitor potential transformer is shown in the figure below. Equivalent circuit when all the quantities are referred to secondary side. The voltage applied to the primary of the intermediate transformer is usually of the order 10kv. Equivalent circuit when all the quantities are referred to primary side.
