1. Competitive Arena
The contemporary landscape witnesses a pervasive concern regarding transformer safety, transcending the boundaries of developed and developing nations. Transformer malfunctions, characterized by arcs, discharges, and intense combustion, can lead to electrical maladies such as short circuits, equipment shutdowns, lighting failures, and even catastrophic fires, with fatal consequences. Consequently, ensuring the reliable and safe performance of transformers is a universal endeavor.
Transformer oil, the cornerstone insulating material, plays a crucial role in maintaining the integrity of transformers and the power system as a whole. Since its inception as transformer oil in 1887, mineral oil has maintained its stronghold due to its accessibility, cost-effectiveness, and high performance. In 1931, polychlorinated biphenyls (PCBs) emerged as a synthetic contender, and silicone oil followed suit in 1956 as an insulating fluid. Nevertheless, mineral transformer oil remains paramount in safeguarding electrical insulation.
2. Physical and Chemical Performance Testing
Moisture content: moisture is an important factor affecting the insulating properties of transformer oil, need to test the moisture content to ensure that the insulating properties of the oil is stable.
Viscosity: the viscosity of the transformer oil directly affects its cooling effect, the viscosity should be tested to ensure that it can effectively take away the heat at high temperatures, while at the same time in low temperatures under the fluidity of good.
Flash point and ignition point: these two indicators are used to assess the combustion performance of transformer oil, low flash point and ignition point may mean that the oil is easy to volatilize and burn, increasing the risk of fire.
