Solutions To Protect Cables: Line Current Differential Relays

In the modern power grid, the protection of cable systems is crucial for ensuring reliable and uninterrupted power delivery.  AC cables have significantly different electrical characteristics than overhead transmission lines. This webinar will explore the techniques and technologies used in cable protection and introduce the versatile SEL-787L Line Current Differential Relay. In this webinar, you will learn about:

• Protection techniques for cable systems.
• Principles and advantages of line differential protection in cable systems.
• Phase, ground, and negative-sequence current differential elements and their performance in the SEL-787L.
• Line current differential protection components that enable the relay to operate securely against CT saturation and communications-related impairments.
