| 摘要 |
Analogue signals corresponding to the electrical parameters of the installation are taken using a single sensor module connected to the electrical installation conductors. The signals are then processed by a central unit where they are converted to digital signals corresponding to the electrical parameters and transmitted via a communications bus to a display for the parameter values.- DETAILED DESCRIPTION - A claim is also made for equipment (2) for making the measurements. A sensor module (3) is connected to conductors (P1,P2,P3,N) of the electrical installation (1) to obtain analogue signals corresponding to the voltages (U1,U2,U3,Un) and intensities (I1,I2,I3,In). A central processing unit (4) is connected to the sensor and a communication bus (5) connects the processor unit to a display and control unit
