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. This voltage is reduced by
approximately half when a container is touched by a hand.
Therefore, this voltage does not present any danger to the user.
