Procedures to qualify PD measuring instruments to use in the insulation condition of cable systems

(ENG)Insulation condition of equipment and materials installed in HVAC and HVDC grids is evaluated using online PD measurements by means of PD analysers operating in the HF range (< 30 MHz). To achieve homogenous and comparable results during on line measurements, calibration of PD quantities and characterization of built in diagnostic tools of PD analysers according to standardized procedures are needed. This paper presents procedures to qualify PD measuring instruments used for insulation condition.(SPA)Se presenta el desarrollo de la primera instalación de precualificación de sistemas de medida de descargas parciales por métodos no convencionales para alta frecuencia comprendida entre 1 MHz y 30 MHz
