Zusammenfassung:	PROBLEM TO BE SOLVED: To correctly determine the power saving capacity at a real time without executing the complicated operation. SOLUTION: A primary voltage V1 and a secondary voltage V2 of a transformer 4, and a primary current I1 of the transformer 4 are detected, and the saved power PS and a power saving rate α are determined on the basis of following expressions; Saved power PS=P1(V12/V22-1) (P1=I1×V1) Power saving rate α=1-(V22÷V12).
