In IEC 60950 for impulse test (6.2.2.1) it is mentioned that "10 impulses of
alternating polarity" to be applied.
Does this means "5 positive and subsequently 5 negative impulses " or "one
positive, second negative, third positivetenth negative" impulses?
Thanks

age and the isolation are the
essential parameters for protection against electric shock.)
In other standards, SELV is determined by the voltage and the isolation from
higher voltages; earthing (or not) of SELV does not enter into this
determination.

Dear All,
IEC 62052-31 is standard for product safety requirements for electricity
metering equipment. It has a table 20 (given below) which details out
insulation requirements between various types of circuits.
My question is, why Basic insulation is required between SELV circuit and
protecti

in general, the test standards prescribe the accuracy / type of equipments and
method to be used for testing. This means that measurement uncertainty has been
specified indirectly. In such cases, where we are following these guidelines,
the pass/fail decision can be taken based on the limits gi
