PROPOSAL FOR ADDITION <strong>OF</strong> IEC 34-4 4 STANDARD IN PART FOR DETERMINATION <strong>OF</strong> POTIER REACTANCE M.M. Kostić* Electrical Engineering Institute Nikola Tesla, Belgrade, SERBIA*
Abstract The author came to the following conclusion: • The Potier reactance value depends almost on turbo generator reactive current (i aQ = i an·sinφ), • This rule is proved by: • general qualitative analysis, and • experiment • Thus, the addition of corresponding standard IEC 34-4/1985: 4/1985: ROTATION ELECTRICAL MACHINES is proposed, i.e. it is proposed that the Potier reactance should be determined from reactive load test: • for the excitation current which corresponds to the rated voltage and armature current value i’ a,cosφ=0 = i an·sinφ n , and • two additional values of reactive load i’ a, cosφ=0 > i an·sinφ n , which are convenient for construction of turbo generator capability (P-Q) curve, for the segment where Q > Q n .
