Measurement and Streaming

SEL measurement and streaming solutions collect high-resolution data from across the power system for analysis, visualization, and real-time decision-making.

Continuous Waveform Streaming

SEL continuous waveform streaming devices deliver high-resolution power system data in real time. These devices stream waveform data to SEL Synchrowave software for visualization, analysis, and historical recording.

Current Transformers

SEL split- and separable-core current transformers (CTs) offer a safe and efficient alternative for retrofits where solid-core CTs are impractical or cost-prohibitive.

Voltage Sensors

SEL voltage sensors provide an easy-to-install replacement for traditional voltage measurement devices, such as potential transformers and elbow voltage sensors, in applications where precise voltage reporting is not required.

Accessories

SEL accessories support the installation, operation, and integration of SEL devices in electric power systems.
