1. Market Trends and Insights
In contemporary times, transformer safety concerns persist across both advanced and emerging economies, posing varying degrees of challenges. Transformer malfunctions often entail arcs, discharges, and intense combustion, subsequently triggering short circuits, equipment failures, power outages, and potentially disastrous fires with human casualties. Hence, ensuring the secure and uninterrupted functioning of transformers is a global priority.
The primary insulating medium within transformers, transformer oil, is pivotal to the safe operation of transformers and the broader power grid. Since 1887, mineral oil has been the traditional choice, while polychlorinated biphenyls (PCBs) emerged as a synthetic alternative in 1931, and silicone oil joined the fray as an insulating fluid in 1956. Given its abundant sources, affordability, and exceptional performance, mineral transformer oil continues to dominate the field, significantly contributing to the insulation of electrical infrastructure.
2. Physical and Chemical Performance Testing
Moisture Level: Moisture significantly influences the insulating capabilities of transformer oil, necessitating moisture content testing to maintain stable insulation properties.
Viscosity Factor: The viscosity of transformer oil is a crucial determinant of its cooling efficiency. Regular viscosity checks ensure optimal heat dissipation at high temperatures while preserving good fluidity at low temperatures.
Flammability Thresholds: Flash point and ignition point serve as benchmarks for evaluating transformer oil's combustion resistance. Lower values indicate heightened volatility and flammability, thereby escalating fire hazards.
