Embodiment Construction

[0039] exist figure 1In the diagram, a measuring device 1 for at least one electrical quantity of an electric current circulating in an electrical installation 2 is schematically shown. The measured electrical quantity can be, for example, a current or a voltage. More particularly, the measuring device 1 is an energy meter configured to measure voltage and current and to calculate the electrical energy and power consumed or provided by the device 2 . The electrical device 2 is preferably a protective device of an electrical system located upstream or downstream of the device 2 . For example, device 2 is a circuit breaker. The electrical device 2 can also be a single-phase or three-phase circuit breaker, with or without neutral. exist figure 1 , a three-phase circuit breaker with neutral 2 is shown. The circuit breaker 2 has the general shape of a parallelepiped, comprising a front surface 2a, a rear surface 2b, two side surfaces 2c, 2d and a first connecting surface 3 com...

Abstract

The invention relates to a device for measuring at least one electrical quantity of a current flowing in an electric apparatus (2), including a main module (20) to be mounted on the electric apparatus (2), the main module (20) including: at least one through-opening (22 to 24) intended for having at least one conductor (8 to 10 and 13 to 15) electrically connected to at least one terminal of the electric apparatus (2) passing therethrough, said through-opening (22 to 24) including connection means (27 to 29) configured such as to be electrically connected to said terminal, characterised in that the main module (20) also comprises: two main connections (30, 31) electrically connected to one another and located respectively on two side surfaces (32, 33) of the main module (20) positioned substantially perpendicular to the first and second surfaces (25, 26).

Description

technical field [0001] The invention relates to the measurement of electrical quantities of electric currents circulating in electrical equipment, in particular electrical energy and power. Background technique [0002] Currently, measuring devices, called energy meters, are used to measure current, voltage, and in particular electrical energy or power consumed or supplied by an electrical system. An electrical system includes one or more electrical devices, and typically includes at least one electrical protection device. These electrical devices are usually installed in electrical cabinets, which do not include a lot of space for housing other measuring equipment. Therefore, it would be advantageous to provide a measuring device that is sufficiently compact and at the same time robust and efficient. [0003] Furthermore, electrical protection devices can have different configurations, depending on the type of distribution (three-phase or single-phase) of the current circ...
