  • Method and device for detecting zero phase component
    Patent number: 9671440
    Abstract: There are provided a method and device for detecting a zero phase component. The device for detecting a zero phase component includes a meter chip of a sequential sampling method, a data acquiring unit configured to acquire sequential data on a plurality of phases from the meter chip, and a zero phase current value calculating unit configured to calculate an instantaneous current value for fault detection by summing instantaneous current values for each phase from the acquired sequential data, and calculate a zero phase current value using the calculated instantaneous current value for fault detection.
