High-Impedance Bus Differential Protection With the SEL-787Z
Date held: Wednesday, July 10, 2024Learn more about high-impedance bus differential protection—and how the new SEL-787Z High-Impedance Differential Relay and SEL-HZM High-Impedance Module provide a next-generation solution.
In this webinar, SEL engineers will discuss how high-impedance bus differential protection works and how new features in the SEL-787Z provide improved protection and ease of use.
The webinar covers:
- The hardware benefits of the SEL-787Z over the SEL-587Z, such as an intuitive touchscreen, faster processing, and a built-in bypass contactor to reduce wiring.
- How the SEL-787Z detects internal faults faster than the SEL-587Z.
- The ability of the SEL-787Z to maintain security during in-zone surge arrester conduction.
- Wiring and setting considerations when applying the SEL-787Z for bus differential protection.
