Hello all:

What can you tell me about these specs.?

        IEEE-C62.41-1991 SURGE voltages in Low-Voltage AC Power Circuits *

        IEEE STD 142-1991  Grounding of Industrial and Commercial Power 

        IEEE STD 519-1992 Harmonic Control in Electric Power Sys. *

        IEEE STD 587-1980 electrical noise immunity spec. *

Are there specified testing procedures to these * marked standards?  

Are there EN or IEC standards that correlate to these standards?

With reference to noise pulses how does
IEEE-C62.41-1991 or IEEE STD 587-1980 apply the
following?  To what environment or connect category? 
That is to say, these wouldn't be applied to single
phase equipment @   5A would they?

        High impedance 6KV amplitude with a 1.2  sec rise time and a 50  sec 
duration.

        Low impedance 3KA amplitude with an 8  sec rise time and 20  sec 
duration 80 joules energy.

        High impedance 6KV amplitude with a .6  sec duration at 100KHZ


        Low impedance 500A amplitude with an .6  sec duration at 100KHZ (4 
joules energy).


For example the proposed specs of EN 61000-4-5 for an
industrial environment (50082-2:1995) indicate 4kVCM
and 2kV DM 1,2/50 (8/20) Tr/Th  sec.  

Another question.  As long as I am bringing up EN
61000-4-5 for an industrial environment.  Would it be
acceptable to specify a CE compliant external surge
suppressor for a piece of CE marked equipment that
would provide compliance to the standard when
used/required in the installation.  This would move
the environment criteria would it not?

Thanks for your comments in advance.
