An electrical device (attachment) for shaping voltage to test the insulation of 6 – 10 kV cable lines is considered. The attachment is capable of generating an ultralow-frequency (0.1 Hz) voltage of 40 kV and a rectified negative-polarity voltage of 60 kV, which allows testing the condition of the insulation of high-voltage cable lines with cross-linked polyethylene insulation and cables with impregnated paper insulation. The device is applicable to 6 – 10 kV distribution networks. It has low weight and dimensions (20 kg and 456 × 363 × 181 mm). Its maximum leakage current is 50 mA. The device can operate from 12 V power supplies, which makes it more mobile. The remote wireless control unit reduces the risk of electrical injuries during high-voltage testing. The attachment is aimed at improving the reliability of the integrated power grid by reducing the number of insulation failures during the transmission of electric power through cable lines of distribution networks.
