Fault Passage Indicators have been used for many years and have evolved from simple blinking light indications to the latest devices that include an array of communications and sensor technology, the Polestar was selected for a trial with the aim of gathering data and developing communications protocols to allow the Fault Passage Indicator (FPI) to communicate with the Control Room Management System (CRMS).

The Polestar device is non-contact and is installed 3 metres below 11kV conductors on the wooden pole. It detects the presence and magnitude of the magnetic and electrical field in the vicinity of the conductor and uses a GSM/GPRS modem to report alarms, routine events and field capture trends to a central iHost Platform.

The project objectives are as follows:

  • Trial the device

  • Develop load monitoring algorithms

  • Evaluate the potential replacement for Power Outage Devices (PODs) on Overhead Line (OHL) networks

  • Feed real-time fault/load data into CRMS

  • Historical load data for planning network reinforcement or development.
