摘要： The invention relates to a three-phase open-core current transformer, preferably for measurement applications, but which can also serve as electrical protection especially designed to be installed over a switch or other type of switchgear device, of those which are installed -generally temporarily- in an electrical installation, such as in a switchboard (where, for example, there are ammeters, energy meters, measurement stations, etc.), and the main function of which is that of measuring, sensing or analysing the current which passes through each cable of the electricity system without having to cut-off the electricity supply.
It is formed by a monoblock body which comprises three individual current sensors, and which is formed by two parts which can be separated from one another, so that it can be opened to be installed with great ease and speed by the operator in a switchboard of a three-phase electrical installation and thus be able to measure the electric current.-

摘要： The invention relates mainly to a compact connection, sensing and measurement device that allows connection to the electrical grid by means of its easy and quick connection to any switching device, such as a magnetothermal switch or differential switch, an on-off switch, an overvoltage protector or the like; wherein its function of collecting and/or injecting signals that are available in the electrical grid, such as voltage or current signals of the electrical grid, and wherein the accuracy of the sensed values of the current is greater than 90% and does not require prior calibration before use.
The invention also relates to a system comprising one or more connection, sensing and measuring devices, one or more servers provided with respective databases wirelessly receiving the processed output data transmitted by the one or more devices.
