YTPQC-APF in Hospital

Uncategorizedsfyh
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…
