Title:
METHOD FOR MANAGING A BREAKER AND CONTROLLER OF A BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/227047
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to a method for managing a breaker and a controller of a breaker. In the method, at least one test time interval is obtained, the at least one test time interval is between at least one actuation point and at least one change point for at least one test current that is caused by applying at least one test voltage to a coil of the breaker. A change point is detected for an actual current that is caused by applying an actual voltage to the coil. An actuation point is determined for the actual current at least based on the change point for the actual current and the at least one test time interval. With these embodiments, the actuation point may be determined in a simple way without a need of a voltage sensor being deployed in the breaker.
