Challenges Presented by Water Contamination in Hydraulic and Lube Systems

It is a common saying in the lubrication industry that you should not mingle water and oil. That begs the question, though: what does it mean? It’s true that contaminated water presents problems, but what standards exist for gauging water quality? Can we keep it under control? Is there a foolproof method to get rid […]

How will the problem of trace moisture in Transformer Oil?

As we all know, transformer oil is an insulating oil product with strict moisture requirements, because a small amount of water can reduce the withstand voltage performance of transformer oil, and the dielectric loss will increase, resulting in transformer failure. Therefore, the moisture content of ordinary transformer oil and special transformer oil (ultra-high voltage) should […]

What are the losses of the transformer?

The transmission of the magnetic field is accompanied by loss, which can be divided into the following situations: Eddy current losses Faraday said that a changing magnetic field can generate electricity, and Lenz said that this kind of electricity will hinder the change of the magnetic field, which is called Back EMF. The magnetic core […]
