1、 Ensure product performance and equipment safetyLiquidity control and transportation efficiencyThe fluidity of petroleum products directly affects pumping, pipeline transportation, and atomization effects. Excessive viscosity can lead to increased transportation resistance, increased energy consu
1、 Quality assurance and defect investigationIdentification of process and material defectsThrough routine tests such as DC resistance measurement and transformation ratio testing, problems such as winding breakage, inter turn short circuit, poor welding, and inconsistent wire specifications can be
The testing principle of insulation resistance tester (also known as megohmmeter, shake meter) is based on Ohm's law (R=V/I), which calculates the resistance value of insulation material by applying DC high voltage and measuring leakage current, in order to evaluate its insulation performance. T
1、 Ensure the safety and reliable operation of equipmentPrevent overload riskAccurately measuring the actual capacity of a transformer can avoid its long-term overload operation. Overload can cause abnormal temperature rise in the winding, accelerate insulation aging, and even lead to fire or explo
1、 Core host componentsIntelligent cable fault testerFunction: Fault pre positioning is performed through low-voltage pulse method (measuring low resistance faults) and high-voltage flashover method (measuring high resistance faults), measuring the approximate distance of the fault point, the total
