Protect Multiple Substation Assets Using One Relay: CPC Solutions With the SEL-487E

New enhancements to the SEL-487E Transformer Protection Relay have expanded its capabilities in centralized protection and control (CPC) applications.

In this webinar, presenter Scott Wenke discusses the recent additions to the SEL-487E and the benefits that CPC solutions offer, including:

• The ability to simultaneously protect multiple assets with one relay, using differential elements for dedicated transformer and bus protection as well as distance protection and feeder protection.
• Reduced device count and simplified maintenance—and an easier transition when the CPC solution uses a field-proven relay with familiar logic and settings.
• The flexibility of applying either conventional relays or digital secondary system solutions—such as process bus systems based on SEL Time-Domain Link (TiDL) or IEC 61850 Sampled Values (SV)—in CPC schemes.

We also explore a recent CPC application of the SEL-487E in a distribution substation with a TiDL-based process bus system, touching on key topics such as cost, usability, reliability, and safety.
