The no-load current and no-load speed of the tested motor are measured as 2.1 A and 1016 [min.sup.-1] consecutively.
is the reactive power losses in the steel, [I.sub.0] is the transformer no-load current;
Table 1 Passport data of transformers TP[??]H-80000/110 TP[??]H-63000/110 Rated power 80 63 [S.sub.rat], MVA Short-circuit losses 0.310 0.245 [DELTA][P.sub.k], MW No-load losses 0.0696 0.06 [DELTA][P.sub.0], MW No-load current I0,% 0.5 0.5 Short-circuit voltage 10.5 10.5 [U.sub.K],% K 0.08 0.08
The approximation no- load reactive power ([Q.sub.o]) is calculated according to the following formula [Q.sub.o] = [square root of 3] * 0.9 * V .[I.sub.0] where [I.sub.0] no-load current from reporting test of motor then [Q.sub.o] = [square root of 3] * 0.9 * 6300 * 76.6 = 762.KVAR
LED Dimmers operate on minimal no-load current (10 mA to 15 mA).
Using a threshold tool in the software to set the threshold slightly above the no-load current for the machine, we see the motor has run for 47.8 percent of the period, which almost corresponds to the expected plant uptime of 50 percent.
