摘要

Electronic device fault detector phase and sequence incorrect phase ac power circuits; comprising a prismatic body one of whose side faces shown terminals of power line to analyze, whose signal alternative high tension rectifies and converts low voltage by a circuit converter, as that to exit the convertible signal enters circuit optocoupler makes digital signal passes through a digital circuit detecting whether phases and sequence are correct and activating said digital circuit two circuits formed by diodes leds depending on the sense made that when is correct, is activated contact normally open relay protection, because digital part of the device works through a power supply conventional.
