Information to DIN VDE 0701-0702:2008-06
(Inspection according to repair or modification of electrical equipment, VDE
0701)
(Recurrent test of electrical equipment, VDE 0702)
The relevant original valid directive is decisive for the implementa-
tion of tests or determining limit values!
The following listed tests –
PE conductor resistance (for equipment with PE conductor)
|
Insulation resistance (if technically possible)
|
Leakage current compensation (if insulation resistance test is passed)
|
To test exposed conductive components that are not connected to the
|
PE conductor

PE conductor-resistance

The resistance and integrity of the PE conductor should be measured.
Measurement voltage 4 – 24 V,
Measurement current >200 mA
Limits
< 0.3 Ω to 5m cable length + 0.1 Ω for each additional 7.5 m of cable length
– max. 1 Ω
Important notes
Move the connection cables during measurement.
|
As the test leads resistance is part of the measurement, the test leads
|
should have a good electrical connection.
