Scope

Scope: This standard specifies the usage conditions, technical requirements, structural requirements, test items and test methods, inspection rules, packaging, transportation, installation, and operation and maintenance requirements for capacitive voltage-divider power extraction devices. This standard applies to capacitive voltage-divider power extraction devices with voltages ranging from 6 kV to 20 kV. Main technical content: This document specifies the usage conditions, technical requirements, structural requirements, test items and test methods, inspection rules, packaging, transportation, installation, and operation and maintenance requirements for capacitive voltage-divider power extraction devices. This document proposes test methods for voltage output deviation, output power, output short-circuit protection, output no-load protection, high-low temperature alternation, humidity and heat, salt spray, and solar radiation of capacitive voltage-divider power extraction devices. The performance parameters specified in this document include a partial discharge index requirement of 1.2 Ur and ≤20 pC for capacitive power extraction devices. This document also stipulates that the device should increase the withstand voltage of lightning strikes and be equipped with short-circuit protection and overvoltage protection.
