PRACTICE AND THEORY: HIGH-VOLTAGE LABORATORY TESTING OF NEW ELECTRICAL PRODUCTS

摘要

High voltage is defined by the National Electrical Code (NEC) as any voltage over 600V and by the International Electrotechnical Commission (IEC) as any voltage greater than or equal to 1,000V. NETA uses the IEEE definition: any voltage greater than or equal to 100kV and less than or equal to 230kV. Other standards and industries define high voltage at different levels. This can lead to confusion with regard to nomenclature, but in this case, it is relative to the application. For every normal operating voltage level used by electrical equipment, there is a corresponding test voltage and a method of applying that voltage for a particular type of equipment according to the tests and standards being applied.
