Z type transformer wiring

VII. Notice

1.For having a plurality of contact points of the transformer, so then, tap type, rated high

and low voltage input, in order to make the test results can automatically calculate the

error, and , once rated input data, the test can automatically calculate the error of the

point and the point is which one tap each tap point (i.e. tap a few), do not have to

change the data.

2. Equal division, there is also called the division of distance, voltage combination is

110±8×1.25%/10.0 of the transformer, the 1.25% is equal to the sub level.

3. Rated tapping, the voltage combination of 110±8×1.25%/10.0 transformers, the rated

tapping is 8+1, means 9. Enter the rated bit. This gives an accurate measurement of the

tapping position of the transformer whose rated tapping position is not at the

intermediate point.

4. Turn ratio tester,Applied to three-phase power samples, measured by the ratio

between the high and low voltage, turn ratio is the ratio between high and low voltage

winding circle number.For high pressure is the star (whether or not having a neutral

point), Low voltage transformer delta connection,Variable ratio is the ratio of root turn 3

times. For the low pressure is the star (whether or not having a neutral point), high

voltage transformer is delta connection, turn ratio is 3 times the root variable ratio.
