YTPQC-APF in Hospital

Hospitals are places where reliable power distribution is needed to guarantee patient health and save lives. Continuity and reliability of power supply are extremely important. Automatic power restoration time of different healthcare venues is as follows: category 0 venues t≤15s; category 1 venues 0.5s≤t≤15s; and category 2 venues t≤0.5s.

The Solution ofYTPQC-APF

Harmonics affect lighting stability and interfere with precision medical instruments such as CT scanners, MRI scanners and ECGs, reducing examination accuracy and ultimately affecting physician diagnoses of patients’ conditions. In addition, high volumes of harmonic current also reduce the stability.There are some harmonic problems in Building 3 of Shanghai Tongren Hospital. In order to avoid the impact of harmonics on the normal work of the hospital, a 200A Active Harmonic Filter is installed to control the harmonics

The Technical Performance

After AHF installation, the field harmonic problem has been well improved, and the current distortion rate is reduced from about 12% to about 2%.
