Prototype overhead line FPI equipment will be installed at approximately 10 sites. Locations will be selected based on a range of factors including performance. The circuit selection will also consider the number of customers, the overall length of overhead line associated with the feeder and considerations towards straightforward installation. Monitoring equipment will need to be installed at the selected sites to gather data to support development of the required algorithms. The FPIs will be integrated via a DNP3 interface into Electricity North West’s existing network management system and will be monitored via Nortech’s iHost system.
Benefits
- Development of a Technical Engineering Specification for overhead line fault passage indicators
- Installation and test procedures for overhead line FPIs
- Communication to central system (iHost) with NMS compatibility via SCADA
- Validation of overhead line FPI performance (reliable communications, earth fault detection, overcurrent detection)
