Abstract: To achieve a reduction of power consumption by stopping an inter-node data input/output process and node processing by autonomous control of each node without using a management table. Included are a data processing unit that performs predetermined processing on data input from an upstream node; and a data output management unit that outputs, to a downstream node, the data on which the predetermined processing has been performed in the data processing unit, and monitors a state of the downstream node. The data output management unit controls the data processing unit to stop the data processing in a case of detecting that there is no downstream node using the output data. The stop of node processing and inter-node data input/output are performed upstream in a chain manner.

Abstract: An electrical distribution panel includes a panel box locating a ground bus in electrical connection with a ground input lug, a neutral bus in electrical connection with a neutral input lug, and a primary power bus connected to a power input lug through a main breaker switch. The main breaker switch is operable between an on position in which the primary power bus receives power and an off position in which the primary power bus is disconnected. Primary circuit breakers can be supported in the usual manner in connection with the primary power bus. One or more auxiliary circuit breakers are connected to the power input lug to receive power independently of the main breaker switch. An electrical outlet can thus be integrally supported in one of the side walls of the panel box to receive power independently of the main breaker switch.

Abstract: An object is to provide gas insulated switchgear that is able to inhibit heat generation of a pressure container. Electrically-conductive members that are non-magnetic and have higher electric conductivity than that of the material of which the pressure container is made, are provided on the inside and on the outside of the pressure container, while being positioned along a main bus and being attached via a flange of the pressure container. Thus, eddy current that occurs when an electric current flows through the main bus are caused to flow through the electrically-conductive members having higher electric conductivity than that of the pressure container. Also, a current return path for the eddy current is formed by a flow path including the electrically-conductive members. Consequently, it is possible to reduce the eddy current flowing on the pressure container and to inhibit an increase in the temperature of the pressure container.
