11. Test parameter
Note: For a correct evaluation of the test current / ISO-resistance, a mini-
mum test time off 0.2 s (Diff) is necessary, in all cases.
Calculation of the maximum idle time, with active "ramp-up".
tidle Max =
Ustart (V)
Utest (V) -
ramp-up rate (
V/s)
Calculation of the maximum idle time, with out "ramp-up".
tidle Max = test time (s) - Diff (min 0.2s)
11.6 CALCULATION OF THE IDLE TIME (HV / ISO)
Idle time (0.1 ... 80.0 s) means " no evaluation of the test current / insula-
tion resistance.
