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.
Remote I/O
SEL remote I/O modules transfer data from remote locations over fiber and expand the I/O of SEL relays, automation controllers, and other devices.
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.
Configuration and Visualization Software
SEL software offers powerful tools for configuring devices and visualizing your power system data.
Accessories
SEL accessories support the installation, operation, and integration of SEL devices in electric power systems.
