Lindsey Systems traces back to Lindsey Manufacturing Company, which its founder started in 1947 in a garage in Pasadena, California. The company is now based in Azusa, California, and makes transmission and distribution products for the electric power industry.
It is known for its sensor systems, its SMARTLINE platform for dynamic line ratings, and its Emergency Restoration Systems for transmission lines.
Why buy Lindsey Systems through Ryan Sales
Sensors only pay off when they match the relay, controller or RTU they feed, and a rep helps you get that match right the first time. We work with your protection, automation and transmission planning engineers from selection through commissioning.
- Application help. We help pick sensor type, accuracy class and output (including low energy analog outputs) for the control or relay on the other end.
- Factory access. We connect you with Lindsey engineers on integration, SMARTLINE configuration and line rating methods.
- Quotes and lead times. We get current lead times for sensor retrofits and new-build packages.
- Regional reps. A rep in your part of Texas or Oklahoma supports you from pilot through system rollout.

Frequently asked questions
Who is the Lindsey Systems rep in Texas?
Ryan Sales represents Lindsey Systems in Texas and Oklahoma, covering overhead, underground and substation sensors plus transmission line monitoring. Regional reps serve Central/South Texas, the Gulf Coast, North Texas and Oklahoma, and West Texas. Call (281) 363-1106 or find your rep to reach the right person.
Can Lindsey sensors work with my existing recloser control or relay?
Usually, but it depends on the input the control expects. Lindsey offers conventional sensor outputs and low energy analog (LEA/LPIT) versions, so the right choice follows from your relay or controller model. Send us the make and model and we will confirm compatibility with Lindsey before you order.
How does Lindsey help with FERC Order 881 ambient-adjusted ratings?
Lindsey's SMARTLINE-AAR/881 tool calculates ambient-adjusted ratings, and SMARTLINE-GT and SMARTLINE-TCF add digital twin ratings and capacity forecasting. Line conductor monitors can supply field data. See our FERC Order 881 guide for background on the requirement.
