Comparative tests of flickermeters

It can be shown that different digital flickermeters implementations that meet the performance tests defined in IEC 61000-4-15 can still disagree significantly in some actual measurements. This paper is intended to apply a set of tests proposed by UIE/CIGRE WG 2 to ensure that implementation is correct and different meters will agree with all types of actual measurements. The main objectives are: (i) test how well flickermeters comply with IEC standards, (ii) provide a reproducible method of testing so that tests can be repeated at another time with any flickermeter designed to IEC 61000-4-15, (iii) prepare test data and test programs for distribution to potential flickermeter manufacturers, (iv) gain knowledge about additional functionality or limitations provided by the tested flickermeters. The tests have been performed using five instruments.
