7.Interface Security Requirement: The configuration of external sensors for the detection device should not interfereGISThe sealing performance of the disk insulator structure and the grounding and current conduction performance of the housing. The installation of external sensors should, in principle, not require disassembly.GISAll components must meet the necessary safety requirements for the installation of detection equipment. This includes: having an adequate safe distance from nearby high-voltage live components and areas; providing effective protection against lightning, overvoltage from switch operations, and rising ground potential; not causing any safety hazards related to power supply, electromagnetic compatibility, and network communication, and not affecting the safe operation of other systems within the substation.
