APPARATUS AND METHOD FOR DETECTING LINE CONNECTING DEFAULT OF SMART METER

摘要

PURPOSE: A misconnection detecting device and a method thereof are provided to omit hardware construction and a phase angle calculation algorithm required for sensing misconnection and a phase angle. CONSTITUTION: A misconnection detecting device(100) includes a parameter calculation unit(140) and a misconnection determination unit(150). A parameter calculation unit calculates a misconnection parameter including three phase effective voltage values, effective current value, effective voltage amount values, and ineffective voltage amount values. A misconnection determination unit determines a misconnection standard by setting the misconnection standard for sensing misconnection in a smart meter.
