Summary
This paper quantifies the environmental benefits of integrating low-power instrument transformers (LPITs) into medium voltage gas-insulated switchgear (GIS) using a cradle-tograve Life Cycle Assessment (LCA) focused on carbon dioxide (CO₂) emission reduction.
Read more Read lessMotivated by the rapid expansion of LPITs over the past decade driven by their application in digital protection systems, IEC 61850 communication, and the use of Sampled Measured
Values (SMVs) within Process Bus architectures the study evaluates LPITs that achieve accuracy class 0.2(S) and operate with MID certified revenue meters. This capability enables
LPITs to replace conventional current and voltage instrument transformers for both protection and revenue metering in medium voltage switchgear. Comparative LCA of LPIT based versus conventional GIS configurations indicates a significant decrease in environmental impacts, with pronounced reductions in CO₂ emissions attributable to lower material intensity and streamlined system integration. The results support the broader adoption of LPITs as a practical pathway to more sustainable, digitally enabled power distribution systems.
