Fault diagnosis system, fault diagnosis device, fault diagnosis method, program, computer-readable medium, and device under test
A fault diagnosis method utilizing a fault diagnosis system for diagnosing a photovoltaic module by estimating a fault location, the fault diagnosis system including a signal generator for generating and inputting an input signal into a positive terminal or a negative terminal of the photovoltaic module, a waveform observer for observing a reflected output signal from an open end or the fault location, a diagnosis unit for estimating the fault location based on the output signal, a conductive body, and an alignment unit for controlling the positions of the conductive body and/or the photovoltaic module. The diagnosis method includes controlling the positions of the conductive body and/or the photovoltaic module, observing the output signal of the input signal, and estimating the fault location based on two reflected output signals of input signals inputted into the positive terminal and the negative terminal of the photovoltaic module.
