【 摘 要 】

Partial Discharge (PD) detection aiming at finding the insulation defects make great effort for ensuring the reliability of the electrical equipment. Thus the performances, such as sensitivity and classification and recognition of PD pattern of PD detector need verified. This paper offers an effective tool to evaluate these performances of PD detectors. Design of the system consists of three modules, including PD pattern simulation module, PD pulse sequence generating module, and high voltage simulation module. Example of realization is also given in detail, which takes advantage of Tesla coil structure to generate programmable pulse sequence under the control of embedded system according to PD pattern. After that, the performance analysis of this proposed evaluation system is discussed, the performance evaluation system can simulate PD pulse sequence with controllability of pulse position distribution and randomness of amplitude in a range referring to PRPD pattern from database.
