Resistive Voltage DividerThe internal resistance of the high-voltage resistance divider is pure resistance, with simple structure, convenient use, high accuracy and good stability, and is widely used. The resistive voltage divider is not suitable for measuring higher AC voltage, because it is relate

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
