Important note : Users cannot be edited or removed once added to your Multi user PDF.Specifies the calculation of efficiency (mainly of large generators) from the summation of individual losses or from measurement of total losses, where the losses are deduced from the heat produced by them and dissipated by the coolants or in the surrounding media. This Standard is based on IEC 34-2A:1974.

This Standard specifies methods for determining losses and efficiency that have been devised mainly for large generators, but the principles used can also be applied to other machines.The calorimetric method can be used to determine the efficiency of electrical rotating machinery either -(a) by the determination of the total losses on load; or(b) by the determination of the segregated losses and hence the conventional total loss by summation of the segregated losses.Depending upon the circumstances, calorimetric measurements may be made in two different ways as follows:(i) Measurement of the quantity and rise in temperature of the cooling medium (direct method).(ii) Calibration of the rise in temperature of the cooling medium.The calorimetric measurements should be performed for each cooling circuit, either primary or secondary, separately.The symbols used are shown in Table 1.
