The article presents a new approach to the detection of a very weak electromagnetic (EM) signal, which is generated by partial discharge (PD) in a high-voltage, oil-filled power transformer. The new technique is based on the discrimination of signal acquisitions disturbed by interference; this procedure enables the desired weak signal to pass for further processing. The method was verified via an experiment, in which very short electrical pulses were injected in the transformer vessel by the antenna. The weak pulse signals were successfully detected in the presence of high level of interference.
