6.1.2.Check the voltage ratio of all taps.Refer to standard GB50150-2016.Item8.0.58.0.5 ratio of all taps to meet the following requirements:1 The voltage ratio of all taps should conform to the law of voltage ratio;2. Compared with the nameplate data of the manufacturer, the following provisions shall be met:1) If the voltage class is below 35kV, the allowable deviation of the transformer voltage ratio less than the voltage ratio shall be 1%;2) The allowable deviation of rated subdivision voltage ratio of all other transformers shall not exceed 0.5%;3) The voltage ratio of other taps shall be within 1/10 of the transformer impedance voltage value
