Abstract
A testing device tests an intelligent electronic device of a power system. A PC generates failure data by performing: simulation calculation for a CT and a PT with respect to current waveform data of a current transformer and voltage waveform data of a potential transformer based on a characteristic of an instrument transformer; and simulation calculation for an MU with respect to the current waveform data of the current transformer and the voltage waveform data of the potential transformer based on a characteristic of the MU. The testing device acquires device information data indicating a circuit breaker of the power system, in synchronization with the failure data. The testing device transmits the failure data and the device information data to the intelligent electronic device via a process bus in accordance with a setting of outputting data to the process bus and a setting of sampling.
