Low-cost investment to make data-based decisions on maintenance spendings, resources and planning.
Smart Cable Guard is a sensor-based digital monitoring system that puts owners in complete control of their medium-voltage cable network. Combing patented technology with 24/7 monitoring and support, it detects and locates faults and weak spots in underground cables with unprecedented accuracy. DNV’s Smart Cable Guard is a unique digital monitoring system that delivers complete peace of mind to anyone that owns or operates MV cable networks
Smart Cable Guard is able to monitor long distances of different types and ages of cables, including switchgear and substations with one single unit. Up to 15 kilometres (10 miles) of XLPE cable and 6 kilometres (4 miles) of PLIC cable can be monitored with low noise.
Weak spots and faults in cables can be pinpointed with an accuracy of less than 1 percent of the length of the circuit. We can do even better: actually, we reach an accuracy of 0.3 percent of the length of the circuit.
You will receive information about a fault or weak spot and its location within 5 minutes by SMS and/or email through automated algorithms.
Smart Cable Guard can monitor multiple cable segments of different ages and materials with on system. It monitors, detects and reports faults and partial discharges and their locations, so you own a 2-in-1 system. The system detects 65% of the weak spots and 99% of the faults before they become fatal and cause a unforeseen interruption of the power supply.
Smart Cable Guard is capable of detecting Partial Discharge (PD) activities using two patented time-synchronized sensors which continuously communicate with each other through the cable that is being monitored. The sensors use the live circuit itself to communicate and to check the level of sensitivity that is reached today and for as long as it is monitoring the circuit.
Prevent outages 24/7 by locating weak spots in underground cables with unprecedented accuracy.
Gain smart insights on:
Location of weak spots within 1% of circuit length
When to plan preventive maintenance work
Accurate location of circuit faults due to e.g. excavation works
The overall health condition of the cable circuit
DNV's Smart Cable Guard is an online monitoring platform that puts control room operators of power networks in complete control of their medium-voltage cable network. Its patented technology delivers high quality of service and complete peace of mind to anyone that owns or operates power cable networks.
