Electrical Safety Improvement in Ngaliyan Public Health Facility on Semarang City

Recent medical appliance basically comprises semiconductor, require a proper power quality to maintain its reliable operation. Healthcare facility feature critical services for life saving for the community, therefore, electrical safety awareness and practice for the power distribution is a must for the daily activity. This paper aims at addressing the concerns of electrical safety, including the improving the power quality for the reliability of healthcare equipment. Asset management within medical equipment can be conducted once the public health meets the national and international electrical standard for the minimum operation. Rearrangement of the power cable to meet its constraint and national standard, where essential distribution segregated from the non-essential one, become one of the option. The other option is the shifting the power from an unreliable grid supply to the more reliable supply. Power quality analysis for the main panel have conducted, mainly for the harmonics and neutral current analysis, which are frequently exist in most of the health care services. Those problems within the grid have non-significant values. Our study shows us that power quality problem may arise from the worst electrical design and installation. After the installation rectification, the reliability problem has reduced the frequency and duration of the travel time. Further discussion includes various ways of reducing harmonics in public health facility and equalizing the individual electrical load within 3 phase power supply, while minimizing the harmonic factor.
