Protect and monitor most transformer applications with the powerful SEL-487E Transformer Protection Relay. Apply up to 5 three-phase restraint inputs, three independent restricted earth fault protection elements, and 2 three-phase voltage inputs, all with synchrophasors. Limit transformer damage by responding to internal fault conditions in.. The SEL-411L, SEL-421, SEL-451 support two battery monitors while Transformer thermal monitoring for mineral-oil immersed the SEL-487B, SEL-487E, and SEL-487V support one.

The SEL-487V has phase- and neutral-current unbalance elements and phase- and neutral-voltage differential elements to provide reliable protection for virtually any application. Apply the IEC 60255-149-compliant thermal model to trigger control actions or issue warnings in adverse operating conditions.. SEL SV-Based Solutions Based on the IEC 61850 standard, SV-based solutions maximize flexibility and interoperability. The SEL-487E-5 can be ordered as a merging unit to digitize analog signals from primary equipment and send them using the IEC 61850-9-2 SV protocol to IEC 61850-compliant relays in the control house. The SEL-487E-5 can also be.
