| Note: Values underlined are estimates, since the voltage range lies out of the limits of validity of the equations (1)-(3) given by the literature (IES 1968). We have considered the permitted tension values according to the existing norm (DNAEE 047/78). For the 115V tension the permitted range variation is 106 to 121, and for the 127 V tension the permitted interval is 116-132V. These are estimated values according to the literature, variations may occur as results of consumer operation. | ||||||||
