S-520 Power Cable Fault designated instrument sound, and magnetic synchronous technology, and cable test audio signal generator or cable testing high-voltage signal generator with fast, objective measure of the power cable low resistance, high resistance and flashover fault precise location, and can be used to find the cable paths, cable identification and depth measurements. 

 Features 
 ◎ fully functional, fixed and cable path to determine a variety of cable fault. 
 ◎ high accuracy, high impedance fault fixed and path detection error does not exceed 0.2 meters, low-impedance fault fixed-point error is not more than 2 meters 
 ◎ simultaneous reception of sounds produced by the cable fault point of discharge and the magnetic field signal, anti-interference ability. 
 ◎ signal waveform of a large screen visual display, easy to identify. 
 The main the ◎ detection waveform recognition, headphone monitoring, supplemented by the elimination of auditory error, the operation is not easy fatigue. 
 ◎ The backlight automatically shut down and charging protection circuit.
