China’s largest sapphire production base——Yunnan Yuxi Crystaland Co.,Ltd. hybrid filter compensation project

10 consecutive years of power quality optimization equipment supply


Existing problems
Large voltage and current distortion rate;
The main harmonic currents were 3rd, 5th, 7th, 11th and 13th currents.
Superposed harmonics resulted in low integral power factor of the system, usually less than 0.75;

Harmonics led to electrical failure, resulting in significant economic losses.


Solution:

ZMAF intelligent modular hybrid filter compensation device was used to make power quality optimization for low voltage system 


Control effect:
The voltage distortion was reduced from 8.3% to 3.3%, and the current distortion was reduced from 19.7% to 8.9%;
5th, 7th, 11th harmonic current distortion rate was reduced respectively from 16.1%, 9.8%, 7.2%, to 7.3%, 3.2%, 2.9%, the filtering effect was very obvious;

Power factor exceeded 0.92
