摘要（英）：

The invention provides an online self-monitoring system for an electronic transformer measurement circuit, which comprises a monitored circuit. The input end of the monitored circuit is electrically connected with a transfer switch; the transfer switch is switched between a waveform generator and a primary sensing unit according to a regular switching signal sent by the monitored circuit CPU; when the transfer switch is switched to the waveform generator, the monitored circuit is in a monitored state, and measurement data are outputted; when the transfer switch is switched to the primary sensing unit, the monitored circuit is in a normal working state, the output end of the monitored circuit is electrically connected with a merging unit comprising a self-monitoring module; the self-monitoring module judges the operation state of the monitored circuit according to the measurement data outputted by the monitored circuit; and the waveform generator generates a standard signal according to the control signal sent by the CPU. Non-stopping power regular automatic monitoring can be realized and the state information is given.
