• High voltage fiberglass telescopic electroscope is used to detect high-voltage AC lines and equipment, whether there is power frequency voltage. It has sound and light warning, so it is safe and reliable. High voltage electroscope is the necessary security tools for electric system and industrial and mining enterprise electricity work. It is used for testing 0.1kV-10kV lines or equipment whether running with power frequency voltage, ensure the personal safety of lineman.
• Used for testing the power frequency voltage on alternating high voltage line and electrical equipment. Function of audible and visual alarm on the safe side.

• Insulation resistance tester has various voltage levels of output, large capacity, strong anti-interference, and the instrument uses high-efficiency batteries. Its operation convenience and safety are obviously better than traditional mechanical megger. It is an ideal test instrument for measuring the insulation resistance of large transformers, mutual inductors, generators, high-voltage motors, power capacitors, power cables, lightning arresters and so on.
