About Linetroll R430D
Linetroll R430D is a smart, reliable fault indicator that keeps your network under control at all times, detecting both earth and short-circuit faults while distinguishing between permanent and transient faults.
Equipped with two individual sensors, the R430D uses both the electrical and electromagnetic field to ensure accurate fault detection across all three phases, eliminating guesswork and reducing time spent on fault location.
When a permanent fault occurs, the high-intensity red strobe-flash LED makes sure you see it, day or night. With an adjustable lens designed for maximum visibility, the indication can be spotted from a long distance, getting your crew to the right location faster and minimizing outage time.
The built-in 4G/LTE modem (with 2G fallback) instantly connects to your central monitoring system and/or sends SMS alerts to one or more recipients the moment a fault is detected. Every message is encrypted and precisely time-tagged using the onboard GPS, giving you accurate, trustworthy data when it matters most.
It is easy to mount on the pole and remains within the safe clearance distance from the overhead line above.
