UT255E is designed with a hook detector, wireless receiver, and telescopic insulating rod. With telescopic insulating rods connected, it can test leakage current, current, frequency, load, and others for bare conductors, bus bars below 35kV, or cables with safety insulation sheaths below 110kV. The hook detector is equipped with the built-in double-layer flexible coil, featuring lightweight, high precision, wide range, and good linearity, it can be hung onto the line for testing, especially suitable for detecting transformer load and inspecting leakage current of multi-core thick cables underground or outdoors.
