Digiphone+ data sheet - .PDF file.

Megger has introduced its Digiphone+ cable-fault pinpointer, which incorporates background noise reduction (BNR) technology and enables the precise locations of faults on buried power cables to be found quickly and easily.

It is based on the technique of comparing acoustic and electromagnetic signals that are produced by flashovers at the fault when a surge voltage is applied to the cable.

According to the company, the difficulty of distinguishing between the acoustic signal produced by the fault and background noise has been solved thanks to the Digiphone+’s ability to compare the acoustic signals produced by two successive flashovers and eliminate all types of noise that are not present in both signals.

The result is a clean acoustic signal that relates only to the fault and, therefore, allows its location to be accurately determined.

The new instrument also features an easy-to-read display that continuously shows the user the distance from the fault and the direction to it. The display positively shows when the fault location is reached and, at this point, it indicates the approximate depth of the fault below ground.

Key features and benefits

  • Digiphone+ quickly and accurately locates cable faults
  • It can indicate when fault location is reached and the approximate depth below ground
  • It can distiniguish between acoustic signal produced by the fault and background noise
  • Volume limiter ensures that the user is not exposed to sounds louder than 84dB(A) in the instrument’s headphones
  • Automatic proximity mute (APM) system mutes the headphones when the operator’s hand approaches the instrument, ensuring that no cracks and bangs are heard when the device is moved from place to place
