Overhead fault indicators
Our fault indicators for overhead lines—whether line-mounted or pole-mounted—offer continuous monitoring of the electrical network to ensure prompt detection and response.
Line mounted fault indicators
Our fault indicators for overhead lines—whether line-mounted or pole-mounted—offer continuous monitoring of the electrical network to ensure prompt detection and response. When an earth fault (EF) or short circuit (SC) occurs, these indicators immediately detect the issue and can report the fault status back to the control center in real-time.
By swiftly pinpointing the location of faults, our fault indicators significantly reduce response times, enabling rapid repair and minimizing downtime. This proactive approach not only ensures a more reliable power supply but also helps to reduce financial penalties associated with unserved energy to an absolute minimum, providing both operational efficiency and cost savings for utility companies.

Pole mounted fault indicators
Our pole-mounted indicators provide a cost-effective solution for fast and reliable fault detection on overhead lines.
Using one single unit installed below the prescribed safety distance, the indicator monitors all three phases and detects both earth faults and short circuits.
With no external connections required, installation is quick and straightforward.
The product can be installed without a live-line team or specialised live-line equipment, helping utilities reduce installation time, complexity and overall costs.
