The Megger Fault Sniffer 2 cable fault detection device is used to quickly locate cable faults in underground low-voltage networks while above ground, without removing the corresponding power line from the mains power supply. The dual sensor installed in the device reacts to the appropriate gases. With cable fault detection, you can detect even the smallest gas concentrations of burnt insulation material above or in the ground.


When a cable fault leads to the burning of the jacket material, combustion gases are produced, the Fault Sniffer 2 reacts to these gases. The combustion gases are directed to the sensors via the integrated pump

The combustion gases are sucked in by a vacuum pump, where sensors in the device detect the gas and display the measured quantities graphically.
Natural occurring gases such as fermentation gas and natural gas are also sucked in and detected. where the two-sensor technology enables the device to distinguish between burning gases and natural gases. If natural gases are detected, the user is warned.

In addition, a vacuum probe system can be connected to direct the gases to the sensors. The sensors used to detect gas concentrations require a running-in period of approximately 1 minute. The running-in phase must be carried out outside. A suitable probe should only be connected after the  running-in phase has been completed.

Various probes can be connected to the Sniffer via the plug-in nipple on the gas inlet. In order to protect the sensors from contamination and the penetration of moisture, a hydrophobic filter and dust filter are located at the gas inlet. Additional protection against moisture is provided by a water blocker, which can also be connected if necessary.

All items are contained in a protective case with a carrying strap. Also available is an extension set vacuum pump system contained in a convenient backpack. Suitable replacement filters for the filter housing at the gas inlet and water blocker can be ordered as accessories.
