Wind Power

SEL products and solutions can protect Type I, II, III, and IV wind turbines and collectors and provide the secure communications needed to synchronize, protect, and control networked generation.

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.

Monitoring, Control, and Integration

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.

Communications and Cybersecurity

SEL communications solutions help ensure that your communications networks are reliable, cybersecure, and compliant with NERC CIP auditing requirements.

SEL-2742S Software-Defined Network 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.
