<p>PROBLEM TO BE SOLVED: To improve potential distribution at a time of applying an impulse voltage by not requiring any insulation reinforcement. SOLUTION: This voltage transformer comprises a high-voltage electrode 11 connected to a bus conductor, a ground electrode 12 connected to the ground, an insulating cylinder 13 that separates the both electrodes, a plurality of resistors R1, R2 which are connected in series between the both electrodes and at least a part of which are arranged on the outer circumference of the insulating cylinder 13, a plurality of capacitors C which are connected in series between the both electrodes and are arranged inside of the insulating cylinder 13, and an intermediate terminal (u) as an output terminal connected to the mutual connection point between resistors R1 and R2. The voltage transformer is constituted by series-connecting a plurality of resistors R1, which are positioned through inside and outside of the insulating cylinder 13, spirally encircling the series-connected body of the capacitors C.</p> |
