Automated instrumentation wiring using interference filters


Posted on Mar 28, 2007

Automated instrumentation wiring using interference filters for the inverter is not as harmonic processing and the like, when the work will be radiated field strength of strong

, high amplitude electromagnetic wave, if the meter is installed in the automation from its lack of 200mm, placed in not the same layer as the shielding box, the meter may yield additional error birth. This time should be the instrument ground terminal properly connected, then the instrument input cable and power cord for the filtering process, as shown in FIG. Now the capacitor C selection 0. lFtF, 250V; inductance L take lOmH, DC resistance of less than 5Q; resistor R to select 100n, 1/2W.
