GB/T 37763-2019
ActiveTechnical specification for CT powered protection device
CT自供电保护装置技术规范
Application Summary AI generated
This standard specifies the technical requirements, test methods, and performance criteria for protection devices that are powered by current transformers (CTs) rather than external power supplies. It is applied in electrical power systems, particularly in medium and high voltage distribution networks, where these devices provide overcurrent and short-circuit protection for equipment like switchgear and transformers in substations. The standard ensures reliable operation of self-powered protection units in scenarios where auxiliary power is unavailable or unreliable.
