Cable Fault Pinpointer
- Finds the fault with unprecedented accuracy
- Offers simple visual directions
- Possesses smart background noise reduction
- Automatically limits audio volume to 84 decibels
- Requires no user adjustments
The Digiphone plus pinpoints underground cable faults with unprecedented accuracy and sets a new standard by applying innovative audio concepts. This combination results in a pinpointing device for high resistive faults that is unsurpassed in sensitivity.
Digiphone plus works off the “thunder and lightning principle” of fault location. In the same way you can measure how far away a storm is by counting the distant between a faster lightning flash and its slower thunder, this pinpointer works by measuring the energy around an underground fault. If you think of the flashover at a fault as the lightning, the Digiphone measures distance by figuring timing between that electromagnetic “flash” and the seismic (or acoustic) jolt also created at the moment of flashover.
- Automatic adaptation to voltage level
- Automatic filtration of interfering signals
- Automatic zero calibration, no adjustments necessary
- History mode
- High-contrast color display
The earth fault locator ESG NT is used to pinpointing cable sheath faults with great accuracy. Using a bright, sun readable TFT color display makes it very easy use.
The displayis by a bargraph, similar to the analogue display or by a history display, which shows the deflections of the last 7 pulses. A fully automatic calibration keeps the display always at zero and the integrated noise suppression eliminates all influences by DC, Railway currents, industrial plants and high resistive soil environment. By two earth rods, the ground step voltage potential is measured and the direction towards the fault is indicated by the display.
The ESG NT is also available as combination set with the digiPHONE+ in one unit.
