Overhead HV fault location solution

Overview

Efficient supply restoration after HV overhead distribution network faults is of critical importance, particularly during storm conditions. Damage to rural sections of network can present safety risks for the public and network repair teams. Faults can be difficult to locate, increasing the time to restore supplies and leaving damaged lines in unsafe conditions.

Currently in development, LineSIGHT is an advanced new monitoring and fault management system and is capable of accurately locating outage issues such as downed lines and low hanging conductors.

LineSIGHT can also detect component deterioration and intermittent problems developing on the network, helping with health assessment and allowing prioritisation of DNOs’ investment in replacement and reinforcement schemes.

Capability

• Rapidly locates cause of outage to within 500m
• Superior detection of hard-to-locate issues associated with broken conductors or pole cross arm connections
• Identifies and locates nested secondary faults
• Assists with automated restoration schemes
• Detects component deterioration and intermittent network problems to give insight into developing faults
