irect current series motor for the operation ofcranes ? &, What effect has an increase or decrease of applied voltageon the speed of an induction motor at no-load and at full-load?Try this experiment. EXPERIMENT 20 Object of Experiment.—To determine the voltage and currentrelations with… … Note.—Each transformer should be protected with fuses incase of short circuit. If for example the third transformer in adelta connected bank was connected as in diagram B, Fig. 449,instead of as in diagram A, there would be a large voltage be-tween points Si and $3, and if they were joined together…
