Abstract
A bypass diode with a disconnection fault is identified. A test device includes: a signal introduction circuit that applies a disconnection position identification signal to between a positive electrode and a negative electrode of a solar battery string; and a fault calculating part that identifies the bypass diode with a disconnection fault on the basis of an AC component of a voltage between a frame ground and the positive electrode or an AC component of a voltage between the frame ground and the negative electrode when the disconnection position identification signal is applied.
