Travelling Wave Recorder – SIPROTEC 7SE20

Why SIPROTEC 7SE20 Travelling Wave Recorder?

The SIPROTEC 7SE20 Travelling Wave Recorder monitors your transmission and distribution lines. It uses the travelling wave method to identify and localize faults on high-voltage power systems.

High-voltage transmission lines are vital for our energy supply, especially for renewable energy transport. Faults on these lines require reliable, quick detection and repair to ensure continuous availability. Our SIPROTEC 7SE20 precisely determines fault positions by measuring travelling waves caused by electrical changes like lightning strikes or short circuits.

Achieve accurate, reliable fault location. Monitor long cable runs, even in difficult areas. Save time locating faults with simple installation; only specify cable length. This ensures quick repairs and improved line availability across overhead, HVDC and sea cables.
