Ametek OCS 500N6 Series - Damped Oscillatory Magnetic Field Testing (IEC 61000-4-10); General Information on Magnetic Field Testing

AMETEK CTS OCS 500 N6 series
Manual for Operation V 5.24 60 / 80
9.
Damped Oscillatory Magnetic Field as per IEC 61000-4-10
For magnetic test a separate manual is damped oscillating magnetic field.
For the magnetic field test, an additional and more detailed operating manual is available. This manual can be
requested if required, or is included in case of an upgrade.
9.1.
General
Damped oscillatory magnetic fields are generated by switching of H.V. circuit breakers or disconnectors.
The test is mainly applicable to electronic equipment to be installed in H.V. sub-stations. Power plants,
switchgear installations, smart grid systems may also be applicable to this standard and may be considered by
Product Committees.
