In the routine maintenance of substations, electrical maintenance in industrial and mining enterprises, and modern production lines, the multimeter is the most frequently used basic measuring instrument by electrical engineers and maintenance electricians.Whether it is checking for continuity in wir
Thermogravimetric analysis (TGA) is a fundamental and crucial testing method in polymer material research and development, insulation material lifespan evaluation, and rubber and plastic component detection. By monitoring the change in sample mass with temperature or time under programmed temperatur
In large thermal power plant turbine units, hydro generator speed control systems, and various heavy-duty high-pressure hydraulic machinery, oil serves as the core medium for transmitting power and lubricating cooling, and is subjected to severe turbulent stirring and shear impact under high-speed m
In motor maintenance workshops, complete electrical assembly lines, and power laboratories, voltage withstand testing of low-voltage electrical components and insulation materials is an essential quality inspection checkpoint. However, in previous practical tests, many testers often faced the proble
Trace leakage detection of sulfur hexafluoride (SF6) gas has always been a key focus for frontline electrical operation and maintenance personnel in power switch stations, GIS combination electrical rooms, and substation maintenance sites. SF6 gas, as an excellent arc extinguishing and insulation me
