Multif-Secondary Voltage Transformer

1) Primary voltage: 200-300 V

2) Transformer to have low flux--low distortion design

3) Number of secondary windings=number of meters to be tested + Wh
standard + spares as required

4) Secondary voltage: 200-300 V

5) Secondary VA rating: 15 VA per winding

6) Insulation secondary to secondary: 500V, 50Hz, 60seconds

7) Primary to secondary ratio accuracy: +/-0.25%(typicl)

8) Secondary to secondary ratio accuracy-less than +/-0.02%

9) Secondary to secondary phase angle accuracy - less than +/- 1
minute

10) Number of secondary output: 1-100

is used to test single phase meter with closed I-P link by producing 1:1 ratio isolation voltage.
