digiPHONE+2
Pinpointing system with surge wave receiver for acoustic and electromagnetic fault location.
Pinpointing system with surge wave receiver for acoustic and electromagnetic fault location.
Key Benefits
- Simple and precise fault pinpointing
- Hear nothing but the cable fault
- Easily visualise the cable route
- The digiPHONE+2 set combines acoustic and electromagnetic fault pinpointing, sheath fault location and tracing in one system for precise fault pinpointing.
Description
The digiPHONE+2 sets a new standard for ease of use and precision, integrating audio and electromagnetic functionality in one user-friendly, colour display. The instrument is highly sensitive, allowing the operator to locate faults in low and medium voltage cables with a high degree of accuracy.
The system comes with a range of features to streamline the fault location process and ensure the operator’s safety.
Intelligent background noise reduction technology produces an undisturbed acoustic experience, ensuring you only hear the fault noise. This means it is possible to lower the surge energy and to find faults in noisy environments.
Auto proximity mute protects your hearing. When the sensor handle is approached, the sound stops before the hand touches the handle – no cracking, no banging. After the sensor has been put down again, a short delay ensures that the digiPHONE+ 2 sensor is standing stable and possible mechanical oscillations have ceased before the headset is activated.
The visual display simplifies cable tracing and keeps you safely on the cable. The compass not only indicates whether you are left or right of the cable, but also in which angle the cable runs to the sensor. The fault arrow indicates in which direction the fault is present. The fault distance can optionally be defined in milliseconds, meters, or feet.

Frequently Asked Questions
How does the digiPHONE+2 surge wave receiver detect cable faults?
A discharge generator feeds surge voltage pulses into the end of the faulty wire. These cause voltage arc-overs at the fault location. The resulting flashover noise propagates in the ground and is recorded with the surge wave receiver on the surface. The distance to the fault location can be calculated using either the volume of the flashover noise or the time difference between the arrival of the magnetic pulse and the flashover noise.
What accessories are available for the digiPHONE+2?
The system can be used for different measuring tasks depending on the measuring accessories connected. The NT set, which includes earth rods, allows the location of the cable sheath faults and ground faults using the voltage gradient method. The NTRX set, which includes earth rods and the Ferrolux receiver, enables the use of routing and expert cable tracing.
