Measurement of substitute leakage current 2
Measuring instruments required: test instrument for leakage current.
• Measure the substitute leakage current according to ARTD-002.731.17...
"Safety regulations for installation and maintenance".
Value first measured 2
When the substitute leakage current is measured, a first measurement and so-called
repeat measurements are carried out. It is the purpose of these repetitions to detect as
early as possible any deviations from the value "first measured" and consequently
changes in the safety structure of the system.
In the measurement of the first value, the permissible maximum value of 2 mA must not
be exceeded.
The value "first measured" has to be entered in the test certificate at the end of the instal-
lation and setting instructions.
Repeat measurements 2
After a repair - if this becomes necessary due to the work performed - and basically
always after maintenance, the substitute leakage current has to be measured again.
The value measured must not exceed the permissible maximum value of 2 mA. In addi-
tion, the value first measured must not be exceeded by more than 50%.
The results have to be documented.
