Only a visual inspection can be done with class-II DUTs that have no ex-
posed conductive components.
Equivalent leakage current
It is mandatory to carry out the equivalent leakage current test even with
good insulation resistance.
Limits
Protection class
DIN VDE 0701
DIN VDE 0702
class-I
< 3.5 mA or 1 mA/kW
class-II
or with exposed conductive component without PE
< 0.5 mA
Important notes
|
The insulation test is only valid when all circuits in the device are acti-
vated.
|
When measuring the PE conductor or contact current, the DUT should
be set in an isolated position and be separated from all other connec-
tions. This is not necessary with differential current measurements. A
measurement is necessary during standard usage in both cases.
|
Reverse the mains power plug (if possible) when the PE conductor cur-
rent, differential current or contact current is measured.
|
Distinguish between equivalent leakage, contact, PE conductor or differ-
ential current.
|
If touch current is measured because a break is not possible, the insula-
tion measurement should be done later.
|
Note the different limit values in DIN VDE0701 Part 1 - 240!
|
With an all-pole disconnecting capacitive circuitry switch, halve the
measured value.
|
Measuring the equivalent leakage current is not suitable for multi-phase
devices.
|
Devices with high leakage current should be marked as such.
