An inspection apparatus for power metering equipment in the present invention may include: a sensing module that measures the voltage and current of a test MOF terminal; a three-phase four-wire power calculation part that calculates a three-phase four-wire power consumption value from the measured values of voltage and current of the MOF terminal; a three-phase three-wire power calculation part that calculates the three-phase three-wire power consumption value from measured values of voltage and current of the MOF terminal; and an MOF inspection part that compares the power consumption values calculated by the three-phase four-wire power calculation part and the three-phase three-wire power calculation part to determine the normality of a test MOF. 본 발명의 전력 계량 기기에 대한 점검 장치는, 피시험 MOF 단자대의 전압 및 전류를 측정하는 센싱 모듈; 상기 MOF 단자대의 전압 및 전류의 측정값으로부터 3상4선식 전력량값을 계산하는 3상4선식 전력 계산부; 상기 MOF 단자대의 전압 및 전류의 측정값으로부터 3상3선식 전력량값을 계산하는 3상3선식 전력 계산부; 및 상기 3상4선식 전력 계산부에서 계산된 전력량값과 상기 3상3선식 전력 계산부에서 계산된 전력량값을 비교하여 피시험 MOF의 정상 여부를 판정하는 MOF 점검부를 포함할 수 있다.
