AUTOMATIC FAILURE RECOVERY, REAL-TIME DETECTION AND DISPLAY APPARATUS IN 3-PHASE POWER SYSTEM

摘要

The present invention relates to an apparatus for automatically recovering a problem on a power quality generated in a three-phase power system, and detecting and displaying the recovered problem in real time. An automatic failure recovery apparatus, in a system having a three-phase four-wire of R, S, T, N or a three-phase three-wire of R, S, T power line supplied to a three-phase load, comprise a failure recovery unit including at least one phase correction means for reducing reactive power and improving a power factor by supplying a diverge line R, S, T, N or R, S, T diverged from each power line as an input, and supplying a phase difference generated in a power line of R, S, T of a three-phase power by regularly correcting the phase difference.
