The core purpose of conducting circuit breaker characteristic testing is to verify whether the circuit breaker can reliably operate in the event of power system faults or abnormalities, ensuring the safe and stable operation of the power system. This can be carried out from the following three key d
1、 Clearly define the test object and scenarioThe insulation characteristics and testing standards of different electrical equipment are different, and instruments need to be selected according to the type, voltage level, and usage environment of the tested equipment:Low voltage equipment (such as
1、 The essence and harm of partial dischargeEarly characterization of concealed insulation defectsPartial discharge occurs inside the insulation system (such as bubbles, impurities, cracks), and non penetrating discharge occurs when the electric field strength exceeds the local breakdown field stre
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
