Hospital is a health service facility provided by the government and the private sector to serve the community strived to prioritize the commitment to provide security and comfort to the community, a hospital building must be made safe and comfortable so that the patients who are being treated therein. The feeling of security arises from the supporting facilities and infrastructure, one of them is the hospital's installation. Hospital installations include several aspects including the electricity distribution system, artificial lighting (lighting), contact boxes, lightning suppliers, and other infrastructure. Therefore, an effort to reduce over design, a hospital electrical installation system is made which processes data to calculate the overall load of the hospital building in a detailed and accurate way and always complies with SNI (Indonesian National Standard). It is expected that with the planning of the electrical installation system is able to support adequate facilities and infrastructure for building users. After planning the electrical installation at the Panti Rahayu Hospital, then the results of the calculation of the installed electrical load is 1331.4 kVA, where with the simultaneity of a load of 70%, the maximum load is 794.4 kVA with a cos cos 0.72 value . To improve the value of cos φ then a capacitor bank of 300 kVAR is needed with a combination of 12 times 25 kVAR on each capacitor so that the normal load can be 626.7 kVAR with cos φ 0.9. The required PLN subscription power supply at this hospital is 865 kVA. Based on the calculation of the total load after repairing the power factor, the capacity of the generator to be installed is 1000 kVA and the capacity of the transformer to be installed is 1250 kVA.
