Standard Voltage Transformer

Main Features

PT of 110/√3 kV, 0.01 class which has high voltage class and high accuracy, this can be used to calibrate the PT 110kV/100V below class 0.05. It can calibrate PT from 20% to 120% of rated voltage. And can be burdened with 0.25VA secondary load when the secondary voltage is 100V.

Technical Data
