SEBA KMT street lighting cable fault locators are compact and reliable for detecting cable faults and measuring lengths of power and motorway telecoms cables with XLPE, PE, PVC insulation.

* Miniflex - lowest cost, user friendly power and comms cable fault locator for use on dead or live cables (blocking filter up to 600v), including twisted pair and coaxial. £756.00 or  £1,061.00 c/w Blocking Filter & VAT - Details Order

* EZ Thump - for difficult cable fault location, eg where expensive traffic management is in place. Battery operated and lightweight Surge Generator and TDR (up to 4kV) enables fault location in a simple step by step process. Sends a brief surge of HV down the cable causing a fault that is normally too high resistance to see with a TDR to break down and "become visible". We then get a distance measurement and switch the unit to "Thump Mode" and use the Digiphone Plus to pinpoint the fault from the surface. £12,079.00 & VAT - Details Order

* Digiphone Plus is used in conjunction with the EZ Thump by HA and street lighting contractors to pinpoint a thump from the surface. Digiphone is unique - actively eliminating noise disturbance, eg traffic. Digiphone informs which direction to go and shows the cable position. £4,480.00 & VAT - Details Order
