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:
Capacitor bank control and feeder monitoring with low-energy analog sensor compatibility and advanced communications components.
A quicker, simpler, and safer solution for controlling capacitor banks, this is the first capacitor bank control to use wireless current sensors.
Optimize system voltage with a voltage regulator control that easily integrates with your distribution automation network.
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.
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 in extreme 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 it for free.
We’re happy to answer all your questions and help develop the best solution for your needs.
SEL support teams are stationed in regional offices around the world and staffed with application engineers who are experts in our products and in power system applications.
Technical support for SEL-manufactured devices is always free. No matter how often you need to call or how long your SEL products have been in service, you’ll reach an SEL expert who can provide the service and support you need.
Our cybersecurity team is always ready with the information and resources needed to keep your OT networks and critical systems secure and working effectively. Cyber services support contracts can include incident response, audits, system hardening, and more, depending on your anticipated needs.
