Applications

– Primary protection and control of distribution feeders for solidly grounded,

high impedance grounded or resonant (Peterson coil) grounded systems

– Busbar blocking/interlocking schemes

– High-speed fault detection for arc-flash mitigation

– Load shedding schemes (bus transfer scheme applications)

– Load shedding schemes based on voltage and frequency elements

– Backup protection for transmission lines, feeders and transformers

– Distributed generation (DG) interconnection protection

Protection and Control

The 750/760 Feeder Protection System is a digital relay for the management, primary protection and control of distribution feeders.

This easy-to-use relay provides comprehensive protection functions for feeders and backup protection for buses,

transformers and transmission lines while reducing product life cycle costs.

Time and Instantaneous Overcurrent

The 750/760 has a two-phase TOC element with level detectors for each phase.

750/760 also has two overcurrent elements, most commonly used for primary and backup protection.
