| Abstract: |
| To realize the stepless and flexible power factor compensation for each phase separately,it is necessary to measure precisely the dynamic power factor of each phase in 3-phase LV system. Combined with the commissioning of practical system,two measuring circuits and their working principles are introduced. One measuring circuit consists of single-chip microprocessor and program-mable timer 8254 and the other consists of single-chip microcomputer and multi-channel analog converting switch CC 4052. |
