This application note describes a prepackaged dual SGC-250 Synchronous Generator Controller solution that reduces engineering and installation time while providing redundant generator control capability. It highlights how the system improves reliability, simplifies integration, and supports utility and industrial power generation applications.

This application note explains the operating principles and application of the ES-47 Phase Sequence Relay for detecting correct phase rotation in three-phase power systems. It describes relay connections, phase sequence identification, and installation considerations for A-B-C and A-C-B system configurations.

This application note explains how the ES-32 Reverse Power Relay improves protection performance by measuring true real power rather than apparent power. It highlights applications for generator protection, loss-of-prime-mover detection, and reverse power monitoring in utility and industrial power systems.

This application note explains how the ES-25 Sync-Check Relay provides enhanced synchronizing supervision by evaluating both voltage magnitude and phase angle differences between a generator and the power system. It highlights methods that improve synchronization accuracy, simplify operation, and help prevent improper breaker closure.
