Hospitals are mission critical applications and require continuous high quality power to achieve the necessary service level. Modern healthcare facilities use expensive medical equipment for intensive care units, surgical operations and other healthcare processes. The dynamic nature of the operation of modern medical equipment may lead to harmonic distortion and other power quality issues. If connected to the public grid, healthcare facilities may also be exposed to power outages and voltage sags. Power quality issues affect the service quality of healthcare providers, their operating costs as well as patient safety and comfort.
