Effects of harmonics 2

[shocker23]

What levels V(THD)are above industry standards in a substation with a capacitor bank. What level of harmonics is acceptable.

I am looking into what levels of harmonics (w/o a study) that can we valadate a need to install a hi-pass filter, in the cap bank curcuit. Im currently researching IEEE 519-1992 but need a little assistance. Section 6.5 refers you to IEEE Std 18-1992 [4] which gives limitations on voltage, current, and reactive power for capacitor banks. These can be used to determine the maximum allow able harmonic levels. I dont have (membership)access to IEEE Std 18-1992 doucment download only the abstract. If there is simular info in IEEE 519 can anyone direct me please.

You might find the attached document of use.
There is more information on the Nokian Capacitors website.

You don't need to be a member to buy IEEE standards, IEEE Std 18-2002 is available to non-members for $106 at

Marmite, thank you for the link. However since I have started knocking down the pages of IEEE 519-1992, I wanted to exhaust 519 before moving on to another document. I found what I was searching for because of it. The objectives of the current limits are to limit the maximum individual frequency voltage harmonic to 3% of the fundamental and the voltage THD to 5% for systems without a major parallel resonance at one of the injected harmonic frequencies. Section 10. Thank U much!

jghirst - You really want me to pay for something I can find free? lol!!~ thanks for the link, I appreciate it! On second thought I would really appreciate if you would pay the $106 for the publication for me! Yea I know - you'll fax me the money, I get it! shocker!
