3 Mode of Operation Layout and mode of Operation I I V V I & V I signal is galvanically separated from the mains network using a transformer. The following mathematical expression is then formed using a RMS value Computer leff= Veff= w T T x i dt o Following filtration by means of an active filter, the transformation properties of the measuring transducer are determined in the characteristics circuit. The o/p amplifier transforms the measuring signal into an impressed o/p signal. The electronic components are supplied with voltage from the mains supply unit. signal is galvanically separated from the mains network using a voltage transformer. The following mathematical expression is then formed using a RMS value computer. w T T x u dt o Following filtration by means of an active filter, the transformation properties of the measuring transducer are determined in the characteristics circuit. The o/p amplifier transforms the measuring signal into an impressed o/p signal. The electronic components are supplied with voltage from the mains supply unit. The Transducer comprises a transformer W, a rectifier unit G and the amplifier V. The measured variable I/U C is isolated from the electronics by the transformer W, and is rectified and a smoothed in the rectifier unit G. The o/p amplifier V amplifies the resultant signal and converts it into the load-indepedent DC o/p signal. The version with live-zero o/p has a m constant current source to provide the zero setting. In the case of -wire connection the o/p increases from the zero setting of m with an increase in measured value. The constant current source needs a supply voltage between and V DC, which may be supply typically from the main installation, the receiving equipments or a separate power pack. Note : For two output, independent sections of Fig & are used. The Transducer comprises a transformer W, a rectifier unit G and a low-pass filter T. The measured variable is isolated from the electronics by the transformer W, and is rectified and a smoothed in the rectifier unit G. I U W Block Diagram leff= w T T x l dt o Fig..
