Muhammadiyah Kendal Islamic Hospital is a business charity that has the task of providing health services. In an effort to fulfill good service, the hospital has two 20kV distribution transformers with a maximum capacity of 197kVA. Almost all installed electrical equipment are equipment with non-linear loads. This study analyzes the quality of electric power which includes power factor, haromisa and load imbalance using the MI metrel 2892 power quality analyzer, so that the value of electrical power in the hospital can be known. Based on the measurement results in the MDP panel one obtained results 5,84% – 12.59% that had met the IEEE 519-1992 standard while in the MDP panel two THDI values were obtained from 6.08% - 20.29% which had exceeded the specified standard. Losses caused by harmonics are equal to 0.834 kW. In the current imbalance obtained a value of 32%. This has exceeded the ANSI C84 standard. 1-1995 which is equal to 20% so that it has an impact on the emergence of neutral currents
