line. Thus ig = (0.0169 —0.0206 y) (3.284+ 1.6667) + (14.77 +1.78^) (635 + iiSj) (3.163 + i.73oy) lo^= 0.1138 — 0.0x457 ampere. The potential difference across the relay at the generatorend of the line is igZt = (O.II38 - 0.01457) (300 + 4717) = 41.0 + 49.37 volts,and, therefore, the voltage… … Fig. 4. which shows the harmonic alternating-current quantitiesas vectors, the generator voltage Ej being the datum phase.The scale of the receiving-end quantities is 5 times as largeas that of the sending-end quantities, all current valuesbeing expressed in milliamperes.
