New UPS and supercapacitor technology at the heart of hospital

Location: Background The most important reason TAYS, Tampere University Hospital, “The most important for the installation of The Pirkanmaa Hospital District Tampere supercapacitor UPSs was for reason for the (PSHP) worked with Eaton their ability to enable peak to install modern UPSs with Challenge: shaving for the generators and installation of supercapacitor technology Peak shaving towards emergency the grid. As a bonus, they also to ensure uninterruptible generators and grid supercapacitor UPSs provide traditional UPS support. operation of hospital imaging The power and back-up power Solution: devices. was their ability for requirements in hospitals have Three paralleled 300 kVA grown more critical alongside Supercapacitor UPSs peak shaving. As In the first phase of the project, Eaton Power Quality hospitals use of electric Results: a bonus they also Oy, which manufacturers UPS equipment and ICT. equipment in Finland, delivered Continuation of operation is “At first, we had planned to provide traditional UPS one 300 kVA UPS with of paramount importance and use DRUPS devices, whereby supercapacitors into Pirkanmaa confidence in the functioning of support.” a diesel rotary generator Hospital District’s cardiology this technology is now proven. powers a UPS.

Challenge Solution Surgery in hospitals is Patient safety is everything. performed with the support of Beyond the large UPSs, CT, computer-based imaging there are imaging devices, devices. Open surgeries are elevators, security systems reduced all the time. This and other devices that need emphasizes the role of the UPS protection. In the past, UPS; if the surgeon’s operating the hospital’s imaging devices screen goes blank during were not even connected to surgery, it is impossible to the emergency generators continue. The UPS supplies because of the power surges the rated power of the CT that occur while doing devices. At the same time, imaging, which could have the supercapacitors supply jeopardized the entire electricity the current peaks of the CT supply from the generator. device imaging function and Consequently, this project has thus also help the emergency delivered a huge improvement, generator. “We are better able thanks to three large UPSs to implement grid protection with supercapacitors that are when we don’t need to take N + 1 connected, i.e. with into account those CT peaks,” redundancy planned into the says Jauhiainen. system. The most challenging in Eaton was chosen largely hospitals is to guarantee because of the hospital’s past the 24/7 operation. Not all experience with the company, activities require this, but so not to mention its heritage built many systems do, that all over 56 years of making UPSs activities need to be organized in Espoo (Finland). According on their basis. Hospitals have to Jauhiainen, “Eaton was operational processes that also chosen because of the staff needs to manage and reliability of its UPSs and the understand. This also means fact that their maintenance and that choice of the device needs technical support have always to be carefully considered, worked well and skillfully. There in order to obtain functional, has always been help available, manageable and practical when it was needed.” Results different electricity supplies, but it also has to be able to systems. Preventive maintenance as a Jauhiainen added that “It is maintain the operations using philosophy is very important The hospital’s 24/7 operation also important that there is a power from the generators. also poses challenges for high degree of domesticity in in hospitals.
