Improve your distribution system’s power factor and voltage stability with a modular, scalable SEL solution.
SEL products give you the flexibility to build a solution one piece at a time, with or without communications, and add capabilities as you go.
A feeder system that has automatic restoration capabilities allows you to take advantage of all the valuable information collected by your relays, automation controllers, and other IEDs to respond to demand in real time.
A complete SEL power quality solution can automatically switch capacitor banks and voltage regulators precisely when they’re needed by the system; there’s no guesswork. It balances voltage and improves the power factor across the system, translating to greater efficiency.
Rugged enough to deploy in harsh environments, our power quality products are tested to the same durability standards as our relays and carry the same ten-year warranty .
Apply SEL power quality solutions for:
- Optimal control of capacitor banks and voltage regulators.
- Power factor improvement.
- Controlling voltage sag and swell.
- Reducing harmonics and transient voltage.
Power Quality Solutions
Let us partner with you to create an SEL solution for your system. From engineering studies and system design through commissioning and training, SEL engineers bring inventiveness and a deep understanding of the fundamental principles of electric power systems to every project.
No matter how complex or sophisticated the system, we can help you protect, simplify, and control it.
Products and Service You Can Rely On
SEL products are designed and manufactured for the world’s most challenging environments, exceeding all industry standards for temperature, shock, and electric stress. An optional conformal coating for circuit boards adds an extra level of protection against contaminants inextreme environments.
Every SEL product comes with a ten-year warranty—the best in the industry. If any product fails under warranty, we’ll repair or replace itfor free.
