Partial discharge usually has a very small amplitude value, but it will cause the continuous deterioration of the insulation layer and finally cause electric equipment fault. Non-intrusive partial discharge detection is used for identifying potential insulation faults that may cause power cutoff or personal injury. The product is an instrument developed for detecting the activities of electromagnetic waves and ultrasonic waves.
