8. Product Information
MBS AG has been developing, producing and marketing current and voltage
transformers for more than 40 years. Our customers rely on the globally
renowned quality of our products.
Production at MBS AG includes current transformers with closed and divided
cores. During the production process, these undergo multiple checks to
ensure they meet MBS AG's quality requirements.
The divided structure of the KBU product group means that these
transformers respond more sensitively to external influences compared to
current transformers with a closed core.
In addition to environmental conditions such as temperature and ambient
humidity, as well as mechanical stress, other factors such as soiling, corrosion
and damage to the interfaces can have an impact on the instrument
transformers' accuracy.
As the manufacturer, MBS AG has no influence over these factors. However
the products are constantly being developed in order to minimise their
impacts.
Some deviations in measuring accuracy caused by these influences,
especially in relation to long-term measuring behaviour, cannot be ruled out
entirely.
The overall errors that occur as a result of the influences set out above are
however generally always within the applicable operating control limits
(the applicable operating control limits are no more than double the standard error value).
