Transformer oil, called insulating oil, plays an important role in cooling and dissipating heat generated during operation. This article will show some factors that contribute to the importance of selecting the right transformer oil.
To make sure the quality and safety operation of the transformer, Users need to check and test them before operation and after operating for a long time. Tests help users easily detect some signs of damage.
The polarity can be defined as the induced voltage direction in the primary windings and the secondary winding. If two transformers can be connected in parallel, then the polarity must be identified for a good connection of the transformer.
This article will introduce a few most common types of MV/HV power substations based on the type of distribution switchgear, which can be seen in every distribution network. There are a number of methods of construction of substations depending on the switchgear type.
The open-circuit test and the short-circuit test are performed on a transformer to determine the equivalent circuit of the transformer, the voltage regulation of the transformer, and efficiency of the transformer.
For the oil-immersed transformer, the transformer oil plays a vital role in insulating and cooling. Therefore, the Acidity Test of Transformer oil is a very essential test for analyzing the oxidation of transformer oil.
