1 падение или повышение напряжения при заданном режиме нагрузки
падение или повышение напряжения при заданном режиме нагрузки
Разность между напряжением холостого хода обмотки и напряжением на ее выводах при заданных нагрузке и коэффициенте мощности при условии, что к другой (или к одной из других) обмотке(ок) подведено напряжение, равное:
- номинальному, если трансформатор включен на основное ответвление (в этом случае напряжение холостого хода рассматриваемой обмотки равно номинальному);
- напряжению другого ответвления, на которое включен трансформатор. Падение или повышение напряжения обычно выражают в процентах напряжения холостого хода рассматриваемой обмотки.
Примечание — В многообмоточном трансформаторе падение или повышение напряжения зависит от нагрузки и коэффициента мощности не только данной обмотки, но и других обмоток

voltage drop or rise for a specified load condition
voltage regulation for a specified load condition
the arithmetic difference between the no-load voltage of a winding and the voltage developed at the terminals of the same winding at a specified load and power factor, the voltage supplied to (one of) the other winding(s) being equal to:
- its rated value if the transformer is connected on the principal tapping (the no-load voltage of the former winding is then equal to its rated value);
- the tapping voltage if the transformer is connected on another tapping.
This difference is generally expressed as a percentage of the no-load voltage of the former winding
NOTE – For multi-winding transformers, the voltage drop or rise depends not only on the load and power factor of the winding itself, but also on the load and power factor of the other windings

hute ou augmentation de tension pour une condition de charge spécifiée
différence arithmétique entre la tension à vide d'un enroulement et la tension en charge aux bornes du même enroulement pour un courant de charge et un facteur de puissance spécifiés, la tension appliquée à l'autre (ou à l'un des autres) enroulement(s) étant égale:
- à sa valeur assignée, si le transformateur est connecté sur la prise principale (la tension à vide du premier enroulement étant alors égale à sa valeur assignée);
- à la tension de prise si le transformateur est connecté sur une autre prise.
Cette différence s'exprime généralement sous la forme d'un pourcentage de la tension à vide du premier enroulement
NOTE – Pour les transformateurs à plus de deux enroulements, la chute ou l'augmentation de tension dépend non seulement de la charge et du facteur de puissance de l'enroulement lui-même, mais aussi de la charge et du facteur de puissance des autres enroulements.
