Missing phase detector |
摘要 |
A multiphase imbalance monitor utilizes a resistive summing network for sampling the ac voltage in each phase of the system under consideration. The summing network provides a zero voltage output under normal conditions. When a phase imbalance or missing phase condition occurs, the summing network provides a finite output voltage which can be used to actuate indicating and/or interrupting means.
