Embodiment Construction

[0051] in figure 1 Among them, the substation 10 connected to the grid 12 includes: a first panel 14; a second panel 16; a power transformer 18 connected between the first panel 14 and the second panel 16; The intensity of the power system 20.

[0052] The substation 10 can transform the current delivered by the network 12 and having a first alternating voltage into a current having a second alternating voltage.

[0053] The grid 12 is an alternating current network, such as a three-phase network. The power grid 12 is a medium voltage network, that is, a network whose voltage is greater than 1000V and less than 50,000V. The first three-phase voltage is then medium voltage.

[0054] Alternatively, the power grid 12 is a high voltage network, that is, a network with a voltage greater than 50,000V. In other words, the first three-phase voltage is high voltage.

[0055] The first panel 14 includes several incoming lines 22A, 22B, and each incoming line 22A, 22B includes a first 24A, 24...

Abstract

The invention provides a system for calculating an electric quantity relative to an electrical device comprising several secondary electrical conductors electrically connected to an electrical conductor. This system comprises a first module including a wireless transmitter, and a plurality of second modules. Each second module includes a wireless transceiver and a current sensor, and each currentsensor can measure strength of cycled current in at leas tone corresponding conductor in primary and secondary electrical conductors. The first module comprises a first transmitting part transmittinga first time synchronization message to each second module. Each second module comprises first means for receiving the first synchronization message and second transmission means for sending a secondmessage containing at least one intensity value measured by the corresponding current sensor to a third module. The intensity values are preferably measured quasi-simultaneously at synchronization tolerance of an error less than 10 microseconds, and the third module includes a wireless transceiver, a second part receiving the second message and a unit calculating the electric quantity from intensity values received via said second messages.
