This because the actual voltage to earth determ ined the insulation resistance and capacitive reactance each line-to-earth; thus, low (but acceptable) insulation resistance one line can in effect earth and raise the other two line-to-line voltage earth.c. d.168 Table 4.19: Single-phase three two-wire a
