20150120218 | NOVEL METHOD FOR REAL TIME TESTS AND DIAGNOSIS OF PARTIAL DISCHARGE SOURCES IN HIGH VOLTAGE EQUIPMENT AND INSTALLATIONS, WHICH ARE IN SERVICE OR OUT OF SERVICE, AND PHYSICAL SYSTEM FOR THE PRACTICAL USE OF THE METHOD - A method for detecting events associated with partial discharges (PDs) in high voltage equipment and installations diagnoses insulation conditions in real time by using PD signal noise discrimination by the parallel use of multiprocessors, which are additionally used for the discrimination, in real time, of different PD sources located in a single position or in different positions. In order to identify the various PD sources, three-dimensional clusters are formed using the coordinates of three parameters characteristic of each pulse: the parameter associated with the front time of the impulse, the parameter associated with the tail time and the parameter associated with the pulse frequency. The diagnostic method can be performed with grid voltage or independent generators as a voltage source, and the invention particularly relates to a novel voltage source designed therefor. A system for the implementation of the method captures PDs, and performs the necessary analysis and measurement. | 04-30-2015 |
