Abstract: A capacitive voltage transformers for distribution of the power of 10kv high potential line, includes a insulating column with a high potential terminal, a ground terminal and capacitors C1 and C2 in series connection. The column is filled with oilless dry filler. The capacitors C1 and C2 formed by a plurality of separated metallized film capacitors respectively in series or in parallel connection. At the tapping point between the capacitors there is a leading-out terminal of the secondary voltage which is connected to an induction transformer L in parallel. The transformer includes a frame with “C” shaped iron cores and windings wound around the cores. One of the said windings is the primary impedance winding, and the other is the secondary winding of the transformer. There is an over-voltage protector P connected in parallel between the tapping point and ground.
