ASTM D6786Standard Test Method for Particle Count in Mineral Insulating Oil Using Automatic Optical Particle Counters
ASTM D6786用自动光学粒子计数器测定矿质绝缘油中粒子数的标准试验方法
Particles in insulating oil can have a detrimental effect on the dielectric properties of the fluid, depending on the size, concentration, and nature of the particles. The source of these particles can be external contaminants, oil degradation by-products, or internal materials such as metals, carbon, or cellulo
