Automated testing of measurement instruments

Abstract

In these days the term power quality becomes to be significant in industry. Many manufacturers develop equipment for measuring the quality of electrical energy for various applications. However, the qualitative requirements for the operation of these devices are still not precisely defined. So it is not an exception that different manufacturers differently interpret requirements. Then it is more difficult to compare qualitative parameters of these different devices. This paper describes how to test functionality and capability of devices for measuring power quality. Automation of such a process significantly increases tester throughput and brings more consistent results.
