This document was uploaded by me. This part of IEC considers additional requirements concerning bandwidth. Leave a Reply Cancel reply. The EVT shall meet its basic accuracy requirement in 9. This first edition replaces the corresponding specific requirements previously contained in IECpublished in Your basket is empty.
BS EN 60044-7:2000, IEC 60044-7:1999
Accuracy classes for the EVT are based on the requirement that the transformer correction factor TCF shall be within specified limits for the following conditions:. Please support the website and ice the community by sending your documents to us.
However, the reader is encouraged to use its most recent edition. Menu Skip to content. The relationships between the limits of the ratio correction factors and the phase angle for the limiting values of the transformer correction factors TCFs specified in Table 2 are provided by parallelograms that are plotted on graphs in which a phase angle correction factor in minutes appears on the x-axis and a ratio correction factor appears on the y-axis.
