Verification method for on-line monitoring device of double-signal-source capacitive equipment

The invention discloses a verification method for an on-line monitoring device of double-signal-source capacitive equipment. The method includes the steps that (1), a signal source to be measured is selected, if an actual signal source is selected, the step (2) is executed, and if a virtual signal source is selected, the step (4) is executed; (2), the actual signal source is established; (3), the actual signal source is measured, current signals are sampled through a current sensor, detected current signals are standard current signals, signals detected by an on-line monitoring sensor of the capacitive equipment to be detected are detected current signals, and then the step (6) is executed; (4), the virtual signal source is established; (5), the virtual signal source is measured, current signals generated by the virtual signal source are standard current signals, and current signals detected by the on-line monitoring device sensor of the capacitive equipment are detected current signals; (6), the detected current signals and the standard current signals obtained in the step (3) or the step (5) are compared for analysis, so that the on-line monitoring device is detected . Means of verification comparison on the on-line monitoring device are enriched, and operation reliability of the equipment is improved.
