Kehui Electric T-506

Manufacturer KEHUI
Model T-506                               

The T-506 is used together with a high voltage surge generator, to pinpoint high resistance and flashover faults on power cables. It utilises an Application (App) running on an Android device, connected wirelessly to a hand-held sensor. The sensor detects magnetic and audio signals emanating from the faulted cable. Although most Android tablets can be used, a pre-programmed, ruggedised device, with a hands-free neck strap, is available from Kehui.

The Tablet has two modes; the Operator mode provides an intuitive indication of the position of the cable, with an arrow showing the position of the fault relative to the user’s position. The Waveform Analysis mode allows the user to diagnose the fault position from the magnetic field and audio waveforms.

The equipment is complemented by a pair of noise-cancelling earphones to assist the user in hearing the sound of the discharge at the fault position in a noisy environment.
