Abstract
The present invention relates to a simple detector for partial discharge with the acoustic emission technique, which provides essentially with an acoustic emission sensor being set on a power equipment. Still, the output of the acoustic emission sensor is connected with a preamplifier and a bandpass filter in turn and the output of the bandpass fitted up with a comparator. The signals of square waves generated by the comparator can be transmitted to a microprocessor as concurrently as a counter in the microprocessor can be used to count up times for partial discharge by seconds; then, the resulted times can be displayed. Consequently, it is convenient to determine whether the power equipment is necessarily maintained by means of counting up times for partial discharge.
