SSTDR in Utilities
Utility companies face numerous challenges in maintaining services and ensuring safety, while rolling out smarter network technology. The cabling infrastructure that physically connects the customer premises to the power distribution network varies in type, length and in the way it is connected to the network. Issues with cable damage, deterioration and tampering often remain undetected unless the cable damage leads to a power outage. Even then, detection is often down to the customer noticing power loss unless the meter is equipped to notify the utility company of the outage. In addition to damage or cable failure, cable tampering to enable power theft is an increasing issue worldwide.
To detect and locate these faults or tamper events requires the capability to see what is happening within the infrastructure while operational. To ‘look into’ cabling infrastructure while it is in operation, requires the monitoring system to be able to sense faults while power and communications are present, without interfering with the operation of the infrastructure being monitored. This has been achieved by using SSTDR. This capability also enables real time detection of unauthorised cable/wire taps for the purposes of power theft.
Whether the SSTDR capability is built into a device such as a smart meter, or is utilised within engineer site test equipment, power utilities can now monitor for faults in real time, speed up the location of both permanent and intermittent issues and prove power theft events without taking the customer out of service.
