METHOD FOR ASSESSING AND QUALIFYING THE FUNCTIONAL FEATURES OF INSTRUMENTS FOR MEASUREMENT AND DIAGNOSIS OF PARTIAL DISCHARGES AND FACILITY FOR GENERATING SERIES OF REFERENCE PULSES OF PARTIAL DISCHARGES

摘要

Method for evaluating and qualifying of the functional characteristics of PD measuring and diagnostic instruments, which comprises the following stages:- generation (1) either from a scale HV testing setup (100) or from an arbritary function generator of at least one PD reference pulse test series characteristic of a type of electrical defects representative of HV grids,- generation of at least one electrical noise signal (9),- superposition (14) without galvanic connection of one or more of the series of PD reference pulses generated corresponding to a specific functional characteristic of the measuring and diagnostic instrument for discrete values of charge and of the generated electrical noise signal(s), and- Evaluation and qualification (15) of said functional characteristic of the measuring and diagnostic instrument, supplying the superposition of signals and reading to compare with the expected values.
