BE1_25_SYNC
Basler-shaped synchronism-check element (ANSI 25) issuing a close permissive on breaker-close-time-compensated phase angle, with dead-line and dead-bus options.
When to use it
Use BE1_25_SYNC when a breaker paralleling two energised sources must only be closed when the two sides are close enough in voltage, frequency and phase, and where a dead-line or dead-bus close is separately permitted.
