Maximum system leakage capacitances for the insulation fault lo-
cation system EDS470
Curve 2a:
Maximum allowable system leakage capacitance in relation to the system vol-
tage to be monitored. Up to this limiting value of the system leakage capaci-
tance, the EDS system has the sensitivity illustrated in curve 1a.
Curve 2b:
Maximum allowable system leakage capacitance in relation to the system vol-
tage to be monitored. Up to this limiting value of the system leakage capaci-
tance, the EDS470 system has the sensitivity shown in curve 1b.
