Transmission lines are often located in mountainous or remote areas, making on-foot or helicopter inspections difficult, time-consuming, and dangerous.  Inspections rely on manual labor that doesn’t always capture accurate data for a proper assessment.  Manual inspections are not only time-consuming, they’re expensive: inspecting 150 miles of power lines and 2,000+ transmission poles take nearly two weeks when performed on foot of 15 employees. It can take one day by helicopter, but the cost can be prohibitive and the data quality insufficient.

That’s why Ozarks Electric Cooperative, a non-profit rural electric utility cooperative headquartered in Fayetteville, Arkansas, United States, collaborated with Honeywell to use the latest drone technology in the inspection process of their utility poles and territory.  By using Honeywell’s UAV system, inspecting and providing actionable data took only five days.  In addition to being significantly less expensive, it’s a major benefit in safety: crews can work from a safer location to identify any cracks, vegetation encroachment, frayed electrical wires, or other problems.

Honeywell speeds up the inspection procedure through a drone flight using a hexacopter together with the Gremsy T3 brushless gimbal.

Honeywell’s system was equipped with the Gremsy T3 gimbal,  a camera stabilizer built for doing commercial inspections. It is lightweight and robust (weight of 2.31 lbs for 3.7 lbs payload), capable of producing 360 continuous pan rotations, and able to set home position. The AUX port on Gremsy T3 provides 12V output to power camera and accessories, and its three optional signals pass through gimbal transmit real-time camera and sensor images which the users can then process as needed.

Gremsy T3 is compatible with Pixhawk FC to support its autonomous flight inspection system. It can be controlled via Lightbridge 2 when using A3/N3 FC, and be used with multiple RC such as SBUS, PPM, or SPECTRUM.

Throughout the inspection mission, Gremsy T3 paired perfectly with the drone to perform seamlessly in the air. The gimbal demonstrated the practical and highly efficient operation of the latest drone technology beyond the visual range. That is the power of technology: important for those who operate electric grids, and for anyone who has some form of infrastructure to monitor.
