PURPOSE:To miniaturize a device by connecting each of three sets of bushing provided at a reactor to the power supply side, a resistor parallel with a reactor and a capacitor in series with the former, and providing a bushing current transformer on a bushing on the power supply side. CONSTITUTION:Three sets of bushings 10a, 10b, 10c are provided on a reactor 1. One set of bushings 10a are connected to the power supply side, one set of bushings 10b to a resistor 2 connected to the reactor in parallel and one set of bushings 10c to a capacitor 3 respectively. Then a bushing current transformer 5 is attached to the bushing 10a, and the bushing 10a and the bushing 10b are connected together inside the reactor 1. As a result, the bushing current transformer can be installed as a current transformer so that the whole unit can be miniaturized. |
