This compact acoustic headset, designed and manufactured by K&S Engineering and Scientific Ltd has been developed with state-of-the-art components to not only to achieve superior performance but also to offer the user an acoustic headset that is smaller than equivalent units currently available on the market. Housed in an IP67 enclosure, the unit, which is used in conjunction with a high voltage surge generator, can easily contend with wet conditions.

K&S Engineering and Scientific LTD's Shockwave Detector comes with two built-in meters (an acoustic detector meter and a magnetic detector meter), with the facility to switch between the meters for listening to the ground microphone or listening to the magnetic receiver.

Designed as a headset unit to locate the underground point of fault on buried high voltage cables, through the detection of a shockwave caused by the spark at the point of fault, the unit incorporates a magnetic field detector which responds to the surge current applied to the cable. This in turn causes a pulsed magnetic field to be radiated. The detection of the magnetic field is indicated on the magnetic detection meter which displays the strength of the magnetic field, thereby enabling the user to trace the root of the cable. As the user approaches the point of fault, the spark at the point of fault causes an audible sound to be transmitted which increases the closer the proximity to the fault.

At the point of fault, both the magnetic wave and the acoustic signal coincide. A visual indicator will be given through the meter reading while an audible signal will be generated through the headset. This combination of acoustic and magnetic variances, coupled with both an acoustic and a magnetic display enhances the ability to trace the point of fault.
