NAHJ Standard Voltage Transformer

Product Detailed Description

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.

Technical Data

1. Rated voltage ratio: 110/3 kV /100V0.1));110/3kV/100/3V0.05

2. Rated secondary capacity: 0-0.25VA  CosФ=1.0

3. Accuracy class: Class 0.05

4. Testing voltage: primary winding is 1.2 /1 min voltage withstand . Secondary winding is above earth and 2kV/1min power frequency withstand.

5. Rated frequency:50Hz

6. Maximum working voltage: 76.2kV

7. Inflatable, with SF6, single phase and semi insulating.
