GB/T 4787.1-2021
ActiveGrading capacitors for high-voltage alternating current circuit-breakers—Part 1: General
高压交流断路器用均压电容器 第1部分：总则
Application Summary AI generated
This standard specifies the general requirements, performance parameters, and testing methods for grading capacitors used in high-voltage AC circuit breakers. It is applied in the design, manufacturing, and quality verification of capacitors that ensure even voltage distribution across circuit breaker interrupters, preventing electrical stress concentration. The standard is primarily used by electrical equipment manufacturers and power grid operators in high-voltage transmission and distribution systems.
