  Re: in most industies hormonics present up to some level. what is limit ? and there effect?
Answer
# 1
The permissible harmonic distortion For Volage harmonics it 
is 5% & for current harmonics 10%.

Harmonics cause voltage distortion & losses in system.

Answer
# 2
In an industry harmonics are measured as TOTAL HARMONIC 
DISTORITION (THD), which permissible limit in most of the 
industries is 3%.

No doubt harmonic create losses, moreover puncture of 
Capacitor banks,unwanted heating of motor are also the main 
disadvantages of harmonics.
