Cable Fault Locator Garners Prominence in Detecting Underground Power Network Defects, Finds FMI


Highvoltage power lines are a vital element of contemporary power supply, energy,and automation systems. The past few decades have witnessed countless miles of powercables put through aerially. Carrying the advantages of resistance againstunfavorable weather conditions, underground power line network, however, is garneringpredominance across major regions of the globe. Yet, technicians find itdaunting to locate the exact area of the fault in underground power lines.

Pinpointing the defects in power lines and addressing them becomes quintessential in order to restore power distribution, and minimize downtime. By deploying travelling waves technique, cable fault locators allows quick addressing of detected faults. The approach is immune to series damages of extended transmission lines, making cable fault locators suitable for AC distribution networks as well as HVDC (High Voltage Direct Current) grids.

Recognizing the importance of fault detection in power supply networks, analysts at FMI find that the global cable fault locator market is predicted to observe an impressive Y-o-Y growth rate of ~10% through 2029.

High Demand for Cable Sheath Fault Locator

Cablesheath faults are abnormalities in the external protective layer of cables suchas PVC jackets. Although the faults pose no adverse impact on the electricalperformance of shielded cables, the negative effects become visible duringmedium to long-term operation of cables. In addition, outer sheath abrasion leadsto corrosion of the cable sheath or the neutral wire, resulting in cablefailure.

Cablesheath fault locator, accompanied by bridge measuring techniques, showcases theability of entering conductor materials, and dimensions, thereby increasing theaccuracy of the measurements. Resistance of the cable conductors sheath,core, and ancillary lines are considered instead of the actual faultresistance. As such, fluctuating resistance pattern in the earth remainsnegligible. Further, cable sheath fault locators enable automatic zerobalancing and analysis of fault distance.

E&E and Telecommunication Sectors Show AcceleratingAdoption

Faults in electrical appliances occur due to irregularities in electric circuits resulting in diversion of current from the desired route. Irregularities affect the resistance of cables which when left unattended, hamper the flow of voltage. Cable fault locators measure the length of the cable and compute impedance variation in conductors with metal wires.

Inthe telecommunication sector, the primary application of cable fault locatorsis to maintain the flow of network throughout the cable lines. Consumersrequire undisturbed network while using their mobile phones for variouspurposes. Complying with the requisite, telecommunication operators count oncable fault locators to offer smooth connectivity and check potential defectsin power distribution lines.

Analysts at FMI comment that “In order toproffer uninterrupted energy distribution throughout the geography, industrialoperators are demanding for cable fault operators enabled with advancedtechniques. As the adoption of electronic appliances and gadgets keeps surging,the imperative to provide smooth connectivity to consumers becomes paramount.”
