Abstract
The present disclosure provides apparatus, systems, and methods for preventing out-of-synchronism closing between power systems. An intelligent electronic device (IED) apparatus may include a control component and a delay component. The control component is configured to selectively control opening and closing of a breaker. The control component selectively outputs a close signal to cause the breaker to connect a first portion of a power delivery system to another portion of the power delivery system. The delay component is configured to delay output of the close signal to the breaker. The delay component includes circuitry independent from control by the control component and the delay component is inconfigurable from a remote location.
