Abstract: The present invention relates to an apparatus and a method for wrong wiring detection between a metering out fit (MOF), including a current transformer and a potential transformer, and a power meter. Provided are a connection error detecting apparatus for the MOF and a method which determines connection between a current transformer cell with a voltage transformer cell for the MOF and the power meter by contrasting either a magnetization curve of a current transformer (CT) or a magnetization curve of a potential transformer (PT) for the examined MOF in a state where the MOF is connected to the power meter with the magnetization curve of either the CT or the PT for a previously set MOF. [Reference numerals] (AA,CC) No; (BB,DD) Yes; (EE) End; (S1) Connecting a current transformer to an MOF; (S11) Similar to a PT magnetization curve of a predetermined standard MOF?; (S13) Right wiring; (S15) Wrong wiring; (S17) Display unit; (S3) Applying the current to two terminals of the MOF with the current transformer; (S5) Measuring the voltage for applying the current; (S7) Measuring a current change according to the voltage change; (S9) Similar to a CT magnetization curve of the predetermined standard MOF?
