is it possible do design an electrical equipment to face an less hormonics( not load dependent) or the generating equipment having the internal design factor to reduce the harmonics generation?

if anybody like to discuss/share knowledge in this topic, pls come to mail.

reg.,

Trishla, the issue of harmonics does influence metering accuracy.
It largely depends on the type of meter, are they true RMS, the type of harmonic (Pos, Neg or Zero phase sequence) as to how the metering will be influenced.

Amarie, the equipment we supply (In South Africa) usually follows the following international standards or specifications:
Capacitors Low Voltage – IEEE 18 – 2002
Capacitors Medium Voltage – IEC 60871 parts 1 & 2 (MV being above 690V)
Reactors – IEC 60289

Hope this helps.
