In modern power grids, insulation degradation is a leading cause of high-voltage equipment failure. Accurately detecting early insulation problems is crucial to ensuring safe operation, minimizing downtime, and extending equipment life. Therefore, dielectric loss testing is crucial.

Transformers are the heart of electrical power systems, and ensuring their performance and safety is vital to the stability of the entire power grid. Among the various tests carried out during transformer manufacturing and maintenance, turns ratio testing plays a crucial role. A transformer's turns ratio, the ratio between the number of windings in the primary and secondary coils, directly affects voltage transformation and load balancing. Even a slight deviation can be an early indicator of internal faults, winding damage, or insulation failure.

In the power transmission and distribution industry, sulfur hexafluoride (SF₆) plays a critical role as an insulating and arc-quenching medium in high-voltage switchgear, circuit breakers, transformers, and gas-insulated substations (GIS). Its exceptional dielectric strength, chemical stability, and thermal conductivity make it the gas of choice for ensuring safety and reliability in modern electrical systems.
