| Summary | This standard specifies the method of inductively coupled plasma atomic emission spectrometry (ICP-AES) Determination of metal and pollutants in insulating oil. Specific elements are aluminum, pickaxe, copper, iron, lead, nickel, tin, silicon, silver, sodium, tungsten, zinc and other 12 kinds of elements. This standard uses oil-soluble metal to correct. This standard is similar to GB/T 17476, but the method is different, so the application of insulating oil has a higher sensitivity. This standard applies to the detection of dissolved metal insulating oil (from overheating or arc discharge, or both) and part of the suspended metal particles (usually derived from wear and tear). Insulation oil element concentration exceeds the upper limit of the standard curve, you can add a suitable diluent after dilution measurement, does not affect the precision. Analysis results and the size of suspended particles, the particle size is greater than a few microns measured |
