*Для трансформаторов с расширенным диапазоном первичного тока погрешности при токе 150 % и 200 % номинального первичного тока не превышают пределы допускаемых погрешностей для 120 % номинального первичного тока.

**Для классов точности TPX, TPY, TPZ по ГОСТ Р МЭК 61869-2 значения номинальной вторичной нагрузки S2ном пересчитываются по формуле, В·А:

где  Rb– номинальное values for parameters резистивной нагрузки по ГОСТ Р МЭК 61869-2;

I2ном – номинальный вторичный ток, А.
