An SEL solution can help you meet the highest standards for reliability and security—while also reducing the lifetime cost of ownership. SEL solutions are ideal for:
- Comprehensive protection for generators and collectors.
- Secure communications for generator networking and control.
- Accurate fault indication and location—resolve collector cable faults and return turbines to production faster.
- Protection and control of capacitors for reactive power support.
- Automation, annunciation, precise time, and equipment monitoring for the entire facility.

SEL-735 Power Quality and Revenue Meter
Optimize your system by analyzing data, identifying usage trends, and diagnosing system problems.- Measure and report power quality indicators.
- Meter revenue over a wide current range.
- Log voltage sag, swell, and interruption (VSSI).
- Capture rate-based demand and energy consumption, and apply time-of-use metering.
- Capture waveforms and trigger records.
SEL-2240 Axion
Remote data acquisition in a rugged, modular platform. Choose versions with 4 or 10 slots, and mix and match the modules to fit your application. Each Axion becomes a node in your distributed generation network, sending deterministic fiber-optic communications to a relay or automation controller.Learn moreCommunications and Cybersecurity
SEL communications solutions help ensure that your communications networks are reliable, cybersecure, and compliant with NERC CIP auditing requirements.
SEL-2742 Ethernet Switch
The industry’s first field-hardened software-defined networking (SDN)-enabled switch. Centralized, software-controlled traffic engineering puts you in control of your communications flows and helps secure the cyber and physical interfaces.- Network security—control exactly what is allowed on your network, and eliminate attack-prone networking features.
- Centralized network management and log collection.
- NERC CIP data collection (with the SEL-5056 Software-Defined Network Flow Controller and the SEL Flow Auditor application).
- Synchronized time over LAN.
- Substation deployment—suitable for harsh environments.
