Guidance for determination of clearances, creepage distances and requirements for solid insulation for equipment with a rated voltage above 1 000 V AC and 1 500 V DC, and up to 2 000 V AC and 3 000 V DC
额定电压高于1000V AC和1500V DC 以及小于等于2000V AC和3000V DC的设备的间隙、爬电距离和固体绝缘要求的确定指南
IEC?TS?62993:2017 gives guidance to technical committees which deal with equipment having a rated voltage of more than 1?000?V AC and up to 2?000?V?AC, or a rated voltage?of more than 1?500?V DC and up to 3?000?V?DC. Rated voltages up to 1?000?V?AC and 1?500?V?DC, as well as higher or lower internal voltages, are covered by IEC?60664-1.
This document applies to equipment for use up to 2?000?m above sea level, and provides guidance for use at higher altitudes.
This document gives guidance for clearances, creepage distances and solid insulation for equipment to achieve safety. It includes methods of electric testing.
