Summarize
Power transformers and reactors are valuable assets in the power industry. Real-time monitoring of trace moisture in insulating oil plays a vital role in the safe operation of these valuable assets. Because the existence of moisture will reduce the breakdown voltage of insulating oil and increase dielectric loss, accelerate the degradation and aging of polymer insulation materials, thus reducing the various properties of the insulation system. In serious cases, it will cause insulation breakdown and partial discharge, affecting the safe operation of the power system.
Similarly, for large-scale continuous operation equipment and heavy machinery equipment, real-time monitoring of moisture in lubricating oil and hydraulic oil plays an irreplaceable role in ensuring the normal operation of these key equipment. The existence of moisture will destroy oil film, cause corrosion of metal parts, make lubricating oil or hydraulic oil invalid, shorten the service life of oil, and even cause unplanned shutdown of large machinery, causing serious safety accidents and economic losses.
