Fully automatic capacitance and inductance tester, abbreviated as capacitance and inductance tester. The fully automatic capacitance and inductance tester adopts a bridge circuit structure, with standard capacitors and the tested electrical container as the two arms of the bridge circuit. When measuring the capacitance value of the capacitor, close the…

There may be several reasons why the DC high-voltage generator cannot add high voltage:1. Power issue:The DC high-voltage generator requires a stable and reliable power supply to operate normally. If the power supply voltage is unstable, fluctuates significantly, or the power supply current is insufficient, it may cause the DC…

Dielectric loss refers to the conductivity loss and polarization loss generated by transformer oil under the action of alternating power plants. This type of loss can lead to a decrease in insulation strength and heat transfer performance, ultimately leading to problems such as overheating, damage, and breakdown of the transformer.…

Therefore, for this instrument, its working principle and product characteristics, let me take you to understand.Working principle:The working principle of a transformer ratio tester is…

What is the cause of oil leakage in oil immersed transformers? Next, the editor will give you a brief introduction.1. Welding qualityThe shell of an oil immersed transformer is a combination of welded and connected steel plates. Due to the long weld seam and numerous welded joints, high requirements are…

The fault diagnosis method for oil immersed transformers is to analyze the collected transformer fault information and determine the type of transformer fault based on the data analysis results. During this process, the accuracy of the collected information plays a crucial role in the accuracy of fault diagnosis. There are…

The degradation of transformer insulation is often the result of a combination of multiple factors, not a single factor. Partial discharge is not only the cause of insulation degradation, but also a precursor and manifestation of insulation degradation. The direct causes of partial discharge in transformers usually include:① There are…
