The dielectric withstanding voltage of components depends on materials and the manufacturing process. For improving insulation in components, discharge levels should be defined including Corona discharge, Flashover and Breakdown. Chroma’s 19055 Hipot Analyzer is equipped with a Discharge Level Analysis mode (DLA) for defining the programming voltage, time, counts and limits of those three levels. DLA mode will indicate the withstanding voltage depending on the different level limit beginning with Corona Discharge Start Voltage (CSV), Flashover Start Voltage (FSV), and Breakdown Voltage( BDV). R&D and QC personnel are able to improve insulation by discharge data collection and analysis.
