pects do polyphase induction regu-lators differ in principle from single phase regulators? Ans. The induced voltage in the secondary has a constant REGULATING DEVICES 1,725 value, and the regulation is effected by varying the phase rela-tion between the line voltage and the regulator voltage. Ques.… … Fir.. 2.424.—General Electric direct current (form S) voltage regulator. It consists ofa main control magnet, relay, condenser and reversing switch, as shown in the diagramfig. 2.42S. This regulator cannot be used for compensation of line drop as the current coilis omitted; it is not a switchboard…
