Power source miswiring detection apparatus |
摘要 |
<p>A power source miswiring detection apparatus for detecting a miswiring of wires of a power source, including a pulse generator for generating a first pulse having a pulse width corresponding to a first phase difference between a first pair of two phases of a three-phase alternating power source, and a second pulse having a pulse width corresponding to a second phase difference between a second pair of two phases of the three-phase alternating power source which is different from the first pair of two phases, and a microcomputer for detecting a third phase difference between the first pulse and the second pulse to judge whether the third phase difference is in a predetermined range, and detecting the miswiring if the third phase difference is judged to be out of the predetermined range. <IMAGE></p> |
