Ekip Synchrocheck Module Technical Paper

This technical paper describes the ABB Ekip Synchrocheck module, an accessory that integrates synchronism checking (ANSI-25 function) directly into the Emax 2 low voltage power circuit breaker, eliminating the need for external relays. It details the module's installation, operation in Live Bus and Dead Bus modes, and how it monitors voltage, frequency, and phase angle differences to safely permit closing tie circuit breakers between two sources.
