| 摘要 |
The present invention relates to an apparatus for monitoring power supply and a method for maintaining power supply thereof. The apparatus for monitoring power supply can normally operate by using an AC power source of other power line even when a power line which is connected to a load side terminal of a short circuit is unavailable due to a leakage occurrence in an internal wiring on a leakage circuit breaker side. The present invention can determine that the leakage breaker is operated due to the leakage in the internal wiring and rapidly diagnosticate if the apparatus for monitoring power supply receives the AC power source via a first power line. The present invention manages series electronic equipment operated with a ground wire and the leakage breaker, thereby increasing efficiency and convenience. |
