HV Power Grid Monitoring By Franklin Electric

Transmission line monitoring With Gridsense Line IQ

The Gridsense Line IQ, from Franklin Electric, quickly identifies faults, protects against overload and intelligently monitors lines from 5kV to 138kV. This transmission line monitoring system also provides easy hot stick installation, multiple communication options and doesn’t require any IT infrastructure.

LineIQ monitors overhead network lines up to 138 kV, letting you quickly determine fault location and cause, and quickly restore power even as you prevent future outages. At the system’s heart is an innovative, self-powered sensor easily installed on energized lines. The sensor enables the continuous capture of critical performance data.

GridSense also provides the only true Line Health Monitor available in the market.
