NAHJ Standard Voltage Transformer

Also called name
Precision voltage transformer, voltage transformer for calibration, voltage transformer for verification, standard voltage transformer for calibration, PT standard, standard PT, high precision voltage transformer, high precision PT, self-rising standard voltage transformer, Self-rising transformer, 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.
