The most Convenient Form of the Circle-diagram 415 Multiplying these equations together, we have 4S = flFtany3 = HFtanyi (6). We saw above that AC = HF tan a^, whence CS = AS — AC = HF tan yj — HF tan a^ = HF… … Fig. 412From equation (i8i) on page 401, we know that {i + Ti)KFA\Zj^ — -fa so that CS- ^1 ■ We get, therefore, for the copper loss in the rotor 3V-^2 = 3^1. CS. Subtracting this from the power transmitted to the rotor, we have P = 3.Vi.SH = 3.Vi.RT. 4i6 Electrical Engineering This is the power…
