– Equivalent Leakage Current
Measurement
General
Measurement of equivalent leakage current
is stipulated by DIN VDE 0701-0702 after
the insulation test has been passed.
Note!
Measurement of equivalent leakage
current may only be performed after
the installation resistance test has
been passed.
Note!
Equivalent leakage current measure-
ment is not an adequate test method
if the device contains switching ele-
ments which switch all poles,
because circuits downstream from
these are not tested by the measure-
ment. Furthermore, leakage current
caused by inverters cannot be mea-
sured. For this reason, active testing
is generally preferable to this mea-
surement.
Warning: Voltage!
Equivalent Leakage Current Measure-
ment
Testing is conducted with up to
250 V. Current limiting is utilized
(I < 3.5mA), but if the terminals are
touched, electric shock may occur
which could result in consequential
accidents.
