All ARTECHE transformers are tested at our High Voltage laboratories, under the strictest criteria of international standards and/or
under specifi c client standards/specifi cations when so requested. All of it under a thorough quality system, certifi ed under ISO 9001.
However, it is normal for pre-operative tests to be performed in order to confi rm certain important equipment values. The following
is a guide to the most common on-site tests and the proper way to perform them on ARTECHE brand transformers.
This annex applies to the following equipment:
› Current Transformers, CA Series, Models: CA-36..800.
› Inductive Voltage Transformers, UT Series, Models UTx-52..525.
› Combined Transformers, KA Series, Models KA-36..245*.
*For combined transformers, tests will be performed accordingly to the current and inductive voltage parts
