engineering to determine the no-load impedance in the excitation branch of a transformer. In this experiment‚ open-circuit test is conducted on single-phase and three-phase transformer to determine the iron core resistance‚ Rc and magnetized reactance‚ Xm. The purpose of short-circuit test is to determine the series branch parameters of the equivalent circuit of a Real transformer. The series branch parameters is the summation of primary and referred secondary resistances and reactance if refer to primary

Sequences and Convergence Let x1 ‚ x2 ‚ ...‚ xn ‚ ... denote an infinite sequence of elements of a metric space (S‚ d). We use {xn }∞ n=1 (or simply {xn }) to denote such a sequence. Definition 1 Consider x0 ∈ S. We say that the sequence {xn } converges to x0 when n tends to infinity iff: For all > 0‚ there exists N ∈ N such that for all n > N ‚ d(xn ‚ x0 ) < We denote this convergence by lim xn = x0 or simply xn −→ x0 . n→∞ Example 2 Consider the sequence {xn } in R‚ defined by xn = n1 . Then xn
