An Ideal Protection Solution for Pad-Mounted Switchgear
You can now standardize on a single protective device for all your switchgear and pad-mount installations.
New enhancements make the SEL-487E-5 Transformer Protection Relay an ideal solution for protecting six-terminal switchgear and even more versatile as a centralized protection and control solution for small distribution substations:
- Sampled Values (SV) publishing—You can now use the SEL-487E-5 as an intelligent merging unit.
- High-Availability Seamless Redundancy (HSR) protocol—Enable HSR on the process or station bus to connect SEL-487E-5 relays in a ring topology for network redundancy with seamless failover.
- Dynamic voltage source selection—Set the relay to automatically switch to the voltage source that provides the best protection based on system conditions.
- Per-terminal second-harmonic blocking—This optional feature improves security for feeder protection against downstream transformer inrush currents.
