Fig. 312 fall of terminal pressure between open circuit and full load is very small.In a modern generator the pressure wiU fall about 5 per cent, in such a case,while on an external circuit with a power-factor of 075, the drop will benea.rly 20 per cent. … A case of special interest is that in which the external circuit causes thecurrent vector I to lead ahead of the terminal pressure vector V by an angle^ (Fig. 314). This can occur when the circuit contains condensers or over-excited synchronous motors. In such a case the terminal pressure mayexceed…
