Series dedicated to testing in variable speed drive systems. From component testing (routine and type tests) up to combined system testing.
What is a safety coupling? Safety coupling is a mechanical shaft component. It connects two pieces of the shaft. However, it has a special role: to protect the shaft line against excessive torque. That is why it is also referred to as a “mechanical fuse”. Synonyms for safety coupling The Read more
Testing of Converter Transformers This post discusses some aspects associated with testing of converter transformers. Most tests performed on converter duty (VFD) transformers are same as those specified for power transformers. However, there are also few differences which are highlighted in corresponding sections of this article. The aim is to Read more
VFD testing: Introduction Abstract This new series on VFD testing will guide you through various aspects of testing of variable frequency drives (VFD) and drive systems. We will discuss tests required by standards (particularly IEC), factory acceptance tests, site acceptance tests and system tests, such as full load combined test Read more
