the difference between IEC 61000-3-12 and IEEE519

Please share more on IEC 61000-3-12? And what is the difference between IEC 61000-3-12 and IEEE519?

Initially, I have the impression that IEC 61000-3-12 is observing a THDI of 5%.

Re: the difference between IEC 61000-3-12 and IEEE519

Hi Pak,

 

The International Standard IEC 61000-3-12 has been prepared by subcommittee 77A: Low frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.

 

IEC 61000-3-12 Part 3-12: Limits – Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and ≤75 A per phase.

 

This part of IEC 61000 deals with the limitation of harmonic currents injected into the public supply system. The limits given in this International Standard are applicable to electrical and electronic equipment with a rated input current exceeding 16 A and up to and including 75 A per phase, intended to be connected to public low-voltage a.c. AC distribution systems of the
following types:
• nominal voltage up to 240 V, single-phase, two or three wires;
• nominal voltage up to 690 V, three-phase, three or four wires;
• nominal frequency 50 Hz or 60 Hz.
Other distribution systems are excluded. The limits given in this edition apply to equipment when connected to 230/400 V, 50 Hz systems

 

NOTE 1 The limits for the other systems will be added in a future edition of this standard.
NOTE 2 Equipment with a rated input current exceeding 75 A per phase should be considered in the harmonic current requirements for installations. See IEC/TR 61000-3-6 and future IEC/TR 61000-3-14.

 

This standard defines:
a) requirements and emission limits for equipment;
b) methods for type tests and simulations.
Tests according to this International Standard are type tests of complete pieces of equipment.
Conformity with this standard can also be determined by validated simulations

Re: the difference between IEC 61000-3-12 and IEEE519

The limits given apply to 230/400 V, 50 Hz systems. The limits for the other systems will be added in a future edition of this standard.

 

The harmonic current limits specified in the tables apply to each of the line currents and not to current in the neutral conductor.

 

The harmonic current limits are specified in Tables.

Hello @Widiyatmoko ,

 

I took the initiative to post your question into our Global Community:

 

"Power Distribution & Digital forum"

 

We got an answer from @DGonzalez to complement the discussion above.

I hope it will help.
