Abstract: A method of predicting energy consumption in electrical distribution systems includes receiving time-series data of plurality of input variables and output variable of electrical distribution system from one or more sensors, determining first set of input variables based on effects of plurality of input variables on output variable, by associating time-series data of each of plurality of input variables with time-series data of output variable, determining a second set of input variables and one or more dependency parameters, based on dependency between each variable of first set of input variables and output variable, at past time instances, generating network representation indicating second set of input variables, output variable, and one or more dependency parameters.

Abstract: Described herein is a switch pole for a low voltage switching device including an insulating casing defining an internal space with a contact area and an arc-extinguishing area of the switch pole, a fixed contact assembly and a movable contact assembly positioned in the contact area and including, respectively, one or more fixed contacts and one or more movable contacts, which can be mutually coupled or uncoupled, and an arc chamber positioned in the arc-extinguishing area that includes a plurality of parallel arc-breaking plates. The insulating casing includes an insulating wall partially separating the contact area from the arc-extinguishing area and a channel connects the contact area to the arc-extinguishing area. The switch pole further includes an additional arc-breaking element anchored to the insulating wall, passing through the channel of the insulating wall and arranged in electrical connection with a terminal arc-breaking plate of the arc chamber.

Abstract: Described herein is a switching apparatus for low or medium voltage electric grids, which includes one or more electric poles. Each electric pole includes: an outer casing defining an internal volume of the electric pole; a fixed contact assembly accommodated in the internal volume of the electric pole and including a fixed contact member extending along a longitudinal axis of the electric pole; at least one movable contact assembly accommodated in the internal volume of the electric pole; an actuation member accommodated in the internal volume of the electric pole and arranged coaxially and externally relative to the fixed contact member, so that the fixed contact member passes through the actuation member along the longitudinal axis. The actuation member is slidingly movable along the fixed contact member. When moving between the first and second actuation positions, the actuation member transiently couples to each trip mechanism to actuate the trip mechanism.
