FAULT DIAGNOSTICS

7.1

A container presents electric current

7.1.1
Description of the failure
The customer feels a slight electric discharge when touching a
container that is being heated by induction.
7.1.2
Cause
Induction technology uses magnetic fields to cause the
container to heat.
Due to the inductive coupling between the container and the
inductor, the container induces a small part of the voltage to
which the inductor is subject.
7.1.3
Solution
The following should be considered:
The induction plates of BSH comply with all national and
international legislation in force.
Under the least favourable conditions, the contact current
transmitted by the container is 5.3 mA, much less than the
limit of 40 mA.
This current is a measurement taken using a passive power
grid described in legislation, which simulates the impedance of
the human body.
It is completely normal that a measurement made between the
container and the ground connection using a tester give a
value of around 80 V.
approximately half when a container is touched by a hand.

Therefore, this voltage does not present any danger to the user.
