چکیده :
Optical current transformers (OCTs) are increasingly considered as replacements for conventional magnetic current transformers in high-voltage gas-insulated switchgear (GIS), offering reduced size and mass, elimination of saturation, broader frequency response, and lower greenhouse gas impact. While previous research has primarily focused on OCT measurement principles and performance enhancement, a thorough, step-by-step approach to GIS enclosure design, addressing both mechanical and electrical aspects for accommodating a three-phase OCT, remains insufficiently explored. This paper presents a comprehensive methodology encompassing material selection, enclosure geometry, connection methods, fabrication quality control, and internal gas insulation management. Through simulations in COMSOL, the electric field distribution and mechanical stresses under transient lightning conditions are analyzed and optimized. The results demonstrate that suitable geometric modifications (e.g., rounded edges), surface treatments, and appropriate creepage distances can ensure mechanical robustness, reliable insulation, reduced SF6 usage, and improved current measurement accuracy. Consequently, this work delivers a fully documented, practical GIS enclosure design that facilitates safer, more efficient OCT implementation in advanced substations.
