Description
This paper deals with a power supply using switching modulation technique, and its application to the hot-line insulation diagnosis. One of the distinct features of the switching modulation techinque employed in this study is that the zero-phase-sequence voltage with arbitary frequency is generated easily in the three-phase power system. Basic composition is just to add a switching modulation device to the commercial power supply or charged indoor main line. Therefore, it is not necessary to feed a signal current from the signal power supply to the grounding conductor via a pouring transformer as required by current hot-line insulation diagnosis system. <BR>When a power supply using switching modulation technique is used to hot-line insulation diagnosis, it is not necessary to modify or change existing commercial power facility. Therefore, there is a possibility that this may advantageously be used as a power supply for mobile type diagnosis. This paper deals with basic theory of switching modulation technique, and the phase rotation characteristics which play a basic role in three-phase power supply, and summarizes basic composition and performances of a trial manufactured experimental device. Furthermore, results of discussion are introduced concerning the conditions and method of its apllication to indoor wiring of fatories and buildings.
