Transformer local discharging ultra-wide band sensor array positioning system and method thereof

This is a transformer local discharge ultrawide-band sensor array orientation system. Four elements ultrawide-band RF sensor arrays are micro size wide-band antenna and their designed upper limit frequency isn't lower than 6 GHz. The elements aren't in one circumcircle and the space between of element isn't smaller than 80cm. Set each group of sensor array at both side of the transformer iron core. Respectively connect the feeder to the four ultrawide-band amplifiers of 1GHz-6GHz by same length and low wastage high frequency RF cable, and the export ending of amplifier connects to the high-speed collecting figure oscillograph. Test the arriving time difference of the element test single with the others by the sensor array to find the position of the transformer local discharge radiant point. The orientation system and method adopt the existing instrument and achieve the veracious orientation and can be used on line.
