Abstract

PURPOSE:To obtain easily a power feeder as a source for a corona measurement, by a method wherein a constant voltage control circuit is connected to output terminals of a current transformer which encircles a high voltage line through an AC/DC converter. CONSTITUTION:A current transformer 12 is placed so as to encircle a 3.3-6.6kV high voltage distribution line W and an AC/DC converter 4, a constant voltage control circuit 5 and, if necessary, a DC/AC converter 6 are connected to the output terminals of the transformer 12 in cascade. With above method a power source such as an engine generator is not necessary in case of a corona measurement and an AC source can be obtained from the high voltage distribution line. In above configuration a split 3 for coupling with the distribution line W, an annular core 1 and a coil 2 are provided to the curent transformer 12 and the converter 4 is composed of four diode elements connected to form a bride. The circuit 5 is composed of elements such as transistors, resistors, or Zener diods and has a parallel control method of a common regulator. The converter 6 is composed of diodes in the same way as the converter 4.
