Method and device for controlling selectivity of electric equipment

A control device comprising:

• a processing circuit;
• and
• at least one communication circuit communicatively coupled with at least first and second electric equipment devices of a first portion of an electric system,
• wherein the processing circuit is configured to receive a first wiring diagram of the electric system and settings of electrical equipment in the electric system including a set of electric equipment settings of the at least first and second electric equipment devices, each of the at least first and second electric equipment devices including a selectivity control device and a circuit breaker connected to plural different voltage power supplies, wherein each of the first and the second electric equipment device is at least one of electric cabinet, electric cubicle or electric panel;
• the selectivity control device operating to:
• determine selectivity information of the first portion of the electric system according to the wiring diagram and said set of electric equipment settings,
• detect a change of equipment in the first portion of the electric system after the determination of the selectivity information,
• check compatibility between a second set of electric equipment settings and the selectivity information, the second set of electric equipment settings
• corresponding to the first portion of the electric system after the detection of the change of equipment,
• cause a portable device to generate a non-compatibility indication when a checking result indicates non-compatibility between the second set of electric equipment settings and the selectivity information, the portable device being communicatively coupled with the processing circuit, and
• communicating the first selectivity information to respective of the selectivity control devices in the respective each of the at least first and second electric equipment device electrical equipment, and
• controlling the selectivity of the first portion of the electric system based on the compatibility between the second set of electric equipment settings and the first selectivity information.

An electric system, comprising:

• at least first and second electric equipment devices:
• a processing circuit;
• and
• a communication network communicatively coupling the processing circuit with the at least first and second electric equipment device, wherein the processing circuit is configured to
• receive a wiring diagram of the electric system and settings of electrical equipment in the electric system including a first set of electric equipment settings of the at least first and second electric equipment devices, each of the at least first and second electric equipment devices including a selectivity control device and a circuit breaker connected to plural different voltage power supplies, wherein each of the first and the second electric equipment device is at least one of electric cabinet, electric cubicle or electric panel;
• the selectivity control device operating to:
• determine selectivity information of a portion of the electric system that includes the at least first and second electric equipment device electrical equipment device according to the wiring diagram and said set of electric equipment settings,
• detect a change of equipment in the portion of the electric system, check compatibility between a second set of electric equipment settings and the selectivity information, the second set of electric equipment settings corresponding to the portion of the electric system after the detection of the change of equipment,
• cause a portable device to generate non-compatibility indication when a checking result indicates non-compatibility between the second set of electric equipment settings and the selectivity information, the portable device being communicatively coupled with the processing circuit, and
• communicating the first selectivity information to respective of the selectivity control devices in the respective each of the at least first and second electric equipment device electrical equipment and
• controlling the selectivity of the first portion of the electric system based on the compatibility between the second set of electric equipment settings and the first selectivity information.
