WebThe primary rotational frequencies that produce vibrations in cooling towers are as follows: Fan rotational speed. 70-400 revolutions per minute (rpm) Drive motor speed. 600-1,800 rpm. Fan blade passing. Fan speed X number of blades (400-3,000 CPM) Gear mesh (6,000-60,000 cycles per minute) Also, note that variable speed drive motors are ... A large voltage difference gradually creates a conductive leakage path across the surface of the material by forming a carbonized track. Testing method is specified in IEC standard 60112 and ASTM D3638. To measure the tracking, 50 drops of 0.1% ammonium chloride solution are dropped on the material, and the voltage measured for a 3 mm thickness is considered representative of the ma…

WebApr 26, 2016 · PTI与CTI的不同之处在于：CTI改变施加的电压，求得材料的最大耐压值，从而决定起痕指数。. 而PTI所试验的电压是一个点，只表示该点是否能耐受住电压。. 换言之，假设PTI为150V，则说明该材料的漏电起痕性能耐受到150V，而且实际中可能比该值还高。. 另一方面 ...
