The measurement error of the transformer is related to the impedance of the secondary circuit. The increase of the impedance will increase the error, and the accuracy will decrease. Therefore, the external impedance is a key factor in determining the exact level at which the current transformer oper

If the breakdown voltage of the transformer oil is unqualified, it means that the quality of the transformer insulating oil has deteriorated.At this point, we need to conduct a comprehensive analysis through various experiments and operation records. If there is no obvious impurity, color change, an

ZJA Series FR3 Vegetable Transformer Oil Filtration Plant is used to purify used transformer oil, FR3 Vegetable Oil, switchgear oil and different insulating oils. It is also used for purifying insulation oil in all kinds of large power equipments,which are110KV-1000KV. It has different flow rate for
