3
I = E x 2Π x F x C
Similarity: Both IEEE 1159 and IEC 61000 series of standards
are used by engineers with sensitive loads.
4
I = E x 2Π x F x C
Similarity: Both IEEE 1159 and IEC 61000 series of standards
agree on the basic concepts and terminology.

I = E x 2Π x F x C I = E x 2Π x F x C
What it is
What the limits are –Emissions and susceptibility How to measure
IEC 61000-2 standardsWhat, exactly, are the IEC 61000 series of standards?
IEC 61000-3 standards
IEC 61000-4 standards
6
I = E x 2Π x F x C I = E x 2Π x F x C
IEEE 1159 – informative, tutorial, instructive
IEC 61000 series – “Thou shalt…”
Differences between IEEE 1159 and IEC standards#1

I = E x 2Π x F x C I = E x 2Π x F x C
IEEE 1159 – Developed by volunteers.
IEC 61000 series – Developed by assigned national “experts”
Differences between IEEE 1159 and IEC standards#2
10
I = E x 2Π x F x C I = E x 2Π x F x C
IEEE 1159 – Approved by consensus.
IEC 61000 series – Approved by nation voting.
Differences between IEEE 1159 and IEC standards#3

I = E x 2Π x F x C I = E x 2Π x F x C
IEEE 1159 – Not enforced – just informative.
IEC 61000 series – Adopted and enforced as national standards –force of law. Very carefuldrafting!
Differences between IEEE 1159 and IEC standards#4

I = E x 2Π x F x C I = E x 2Π x F x C
Similarities• Cover power quality• Agree on compatibility• Agree on basic concepts• Agree on terminology
Summary – IEEE 1159 and IEC 61000 series
Differences• Tutorial vs “thou shalt”• Volunteer vs appointed experts• Consensus vs national voting• Informative vs enforced
