1) Reduce active power consumption of harmonic cause
2) Safe lifting power factor, avoid the penalty of power factors’ examination from power supply department
3) Eliminate the interference from harmonic to communication signal
4) Secure safety of data center
5) Ensure the safety, steady, reliability of power, improve power quality, make sure communication device to work steady.
The harmonic is very severe in telecom buildings such as communication device, data center device, and special air conditioner device.
Communication room requires high continuity of power supply, very sensitive to voltage fluctuation, various electromagnetic interference will effect data exchange and communication device. Telecom building has large capacity harmonic loads, most are single-phase nonlinear load, including:
1)UPS non-break power device (3times, 5times, 7times) with UPS power, single big capacity, most are 6 pulse wave
2)On-off power, mainly used for computer and other office device, many times(3times, 5times, 7times)
3)Inverter air conditioner, elevator, water pump, etc. Inverter driver device is the main harmonic source.(5times, 7times)

Suggest to use passive filter and active filter to conduct local harmonic control and reactive compensation
1.Use fast filer reactive compensation device, improve power factor safely
2.Use passive filter, can control 5times, 7times, 9times harmonic; prevent harmonic from destroying the communication device, electrical device, reduce active power consumption of harmonic cause; improve the use efficiency of system capacitor and distribution device.
3.Use active filer, eliminate the interference of harmonic and active power consumption; increase the reliability of system’s operation.
4.Use harmonic voltage suppressor to control the 3times, 5times, 7times, 9times harmonic voltage.
