F Measuring high- and low-voltage-side in series
It makes sense to measure the high voltage side in series to the low voltage side to magnetize the
transformer faster. Always select the 2 windings that are on the same part of the core in the same
current direction. In the following table you find examples of transformer connection schemes for
injecting test current and measuring 2 windings simultaneously:
