Mitigating Murphy's Law While Test - Volume 1

At Haefely Hipotronics, we have seen and have even surprisingly discovered situations, in which tests were performed in an improper way: typically Murphy's Law. Various causes are involved, such as misinterpretation of standard (IEC/IEEE), or misinterpretation of the instrument settings, or inadequate instrumentation or test system. Performing tests improperly can lead measurements that do not conform to the applicable (IEC/IEEE) standard or may produce wrong measurement results, that may even damage the test object, test system, or cause injury to the operator. This presentation is a summary of some situations that have been seen onsite, covering tests like partial discharge measurement, loss measurement and lightning impulse test.
