OHL fault locator
- Overhead line fault indicators 6-70kV
Quick location of a fault on a distribution network is critical for electric utilities. Every minute spent searching the wrong section of line extends the outage and increases restoration costs. ATRIY's Lodestar series provides fault indicators for overhead lines rated 6–70 kV: conductor-mounted devices that continuously monitor line conditions and identify problem areas in real time. Because each unit clamps directly onto a live conductor, utilities can deploy these overhead line sensors without causing outages, and crews always know where to respond, rather than simply knowing that something has tripped.
Key Features and Benefits
Lodestar is a compact device that clamps onto a live conductor to continuously monitor line condition. It acts as a short circuit sensor on the overhead line, instantly detecting short-circuit currents and other disturbances in the network.
Unlike basic overhead line fault sensors that only flash a local LED as a warning signal, GSM-equipped Lodestar models immediately transfer information to operators. Maintenance crews no longer need to patrol countless kilometers of line to find a tripped breaker or downed wire — the indicator itself identifies the problem area, leading to faster repairs, improved safety, and significantly reduced downtime.
Key advantages
Accurate detection. Lodestar identifies short circuits and overhead line faults across the network, distinguishing real fault events from transient disturbances and helping crews respond only when necessary.
Automatic remote alerts. As soon as a fault is detected, GSM-equipped models send an immediate alert via 3G/4G to SCADA for real-time monitoring. Operators know when and where a problem has occurred before a crew is even dispatched.
Live-line installation. The conductor-clamp design allows installation on energized 6–70 kV lines without any outage. Utilities deploy the devices without interrupting service to customers.
Line-powered option. The CL0.2B VEH model is powered directly by the line current itself, removing the need for battery maintenance on that variant.
Multiple current ratings. The Lodestar range covers a wide spectrum of network rated currents — from lower-current rural feeders to higher-current distribution lines — within the 6–70 kV voltage class.
Local visual indication. All Lodestar models include optical LED indication on the device. Field crews patrolling a feeder receive immediate visual confirmation of fault passage even without a mobile data connection.
SCADA Integration
Lodestar's built-in GSM communication module sends alerts directly to SCADA (Supervisory Control and Data Acquisition) systems, so operators instantly know when and where a problem occurs. This remote overhead line fault indication enables faster crew dispatch and reduces the time between fault occurrence and restoration.
The connectivity also allows utilities to move from reactive fault management toward a proactive approach: the location of every short circuit on an overhead line becomes known within seconds, and the optimal switching decision can be made immediately. Integration with automated switchgear further speeds up restoration and improves overall network reliability.
ATRIY's Lodestar is a solution that improves distribution network reliability by enabling rapid outage response. By installing these intelligent faulted circuit indicators for overhead lines, utilities can minimize downtime and losses.
Lodestar Series — Model Overview
The Lodestar range for 6–70 kV overhead lines is available in several configurations to suit different network requirements and communication needs:
- GSM Master models (BM): Provide full remote communication via 3G/4G. The master unit transmits fault events directly to SCADA and coordinates with associated slave units on the same feeder section.
- GSM Slave models (BM-S): Work in conjunction with a BM master unit, extending fault detection coverage to additional spans while sharing one communication channel.
- Optical indicator models (B): Feature local LED indication only, with no remote communication. These are suited to networks where remote monitoring infrastructure is not yet in place or where visual patrol is the primary maintenance method.
- Line-powered models: Powered directly by the line current itself, making them self-sustaining on energized conductors without the need for a separate battery.
Frequently Asked Questions
What is the primary function of a fault indicator?
It monitors the line for short circuits and ground faults, providing instant alerts. This helps crews find the damaged section immediately without patrolling the entire feeder.
What is the difference between BM, BM-S, and B models?
- BM (Master): GSM-enabled for remote reporting to SCADA.
- BM-S (Slave): Connects to SCADA via a Master unit to save costs.
- B (Optical): Local LED flashing only, for visual inspection.
Can Lodestar be installed on a live 6–70 kV line?
Yes. The conductor-clamp design allows safe installation on energized lines. No power outage or service interruption is required.
How do I choose the right model?
Selection depends on your network's current, the need for SCADA integration, and your feeder length. Contact ATRIY for a recommendation based on your parameters.
