摘要
In a ground fault detection device, two photovoltaic strings are disconnected from a photovoltaic power generation system, measurement for one photovoltaic string is performed by a measuring instrument, and in parallel therewith, the other photovoltaic string before measurement is charged/discharged by a charging/discharging unit by executing various functions of the calculation control unit. In other words, charging/discharging of the photovoltaic string is performed in advance at the same timing as the measurement of the photovoltaic string so that the measurement can be performed immediately after the photovoltaic string is connected to the measuring instrument in a subsequent step.
