Cable Fault Locating Service
Underground Cable Fault Locating Services
- High voltage cables. (Up to 33KV)
- Low voltage electricity cables
- Communication/Data cables
Basically, it’s a hole, or a crack, burning through the cable.
Underground cable faults can present themselves as a minor inconvenience to private dwellings or a major — and expensive — problem to locate and rectify for commercial and industrial facilities. Our engineer can significantly reduce any problems associated with cable faults by utilizing advanced radio detection locators to locate down to earth cable faults and pinpoint exactly where the fault it. Our radio detection locators allow us to obtain information about the exact location and depth of the fault without placing over stress on the cable. We’re also equipped to handle multiple cable faults at one time.
We understand your urgency and make it our priority to be on site quickly, pinpointing the cable fault and enabling you to resume operation with minimal business interruption. Whether your cables are underground, buried, concealed on cable trays and ladders… if there’s any kind of fault or discontinuity, our specialized equipment can find it. An unexpected blackout due to a cable failure and the associated downtime can cost businesses thousands of rupees per hour. Take the guesswork out of it and call Electrical Testing Company to locate that mysterious cable fault. Using modified “Murray Loop”, Time Domain Reflectometer [TDR], “Popeye” & “Thumper” and the benefit of years of experience, Our Company in most cases pinpoint the trouble spot.

Underground cable fault locating
We find underground cable faults fast, so you dig once
When an underground cable fails, every hour without power costs money, and digging up the wrong stretch of road costs more. Our engineers first pre-locate the fault with a TDR, then pinpoint it with a surge generator and acoustic receiver, so the excavation is done at the right spot.
We locate faults on LT and HT cables up to 33 kV for factories, hospitals, housing societies, campuses and utilities across Uttar Pradesh.
What our cable fault service includes
- Fault type analysis with insulation resistance test
- Cable route tracing where the route is unknown
- Pre-location with TDR (time domain reflectometer)
- Pinpointing with surge generator and acoustic receiver
- Marking the exact digging point
- Supervision of jointing after repair
- HiPot (DC withstand) test before re-energising
- Written report of fault location and test results
Common cable faults we locate
| Fault | Typical cause |
|---|---|
| Low-resistance (short circuit) | Joint failure, mechanical damage during digging |
| High-resistance or flashing fault | Moisture entry, ageing insulation |
| Open conductor | Cable cut or burnt-out joint |
| Sheath fault | Damage to the outer sheath that will lead to failure later |

Questions
How quickly can you reach the site?
We are based in Lucknow, so we can reach most sites in the city quickly. For other cities in Uttar Pradesh we plan the visit with you.
Do you locate faults in HT cables?
Yes. We locate faults in LT and HT underground cables up to 33 kV.
Do you also repair the cable?
Yes. Our team can make the cable joint or termination and test the cable before it is switched on. See cable laying and jointing.
What if we do not know the cable route?
We trace the route with a cable locator before pinpointing the fault.
