Electrical energy is indispensable in people's lives for the sake of survival and for life on the work. Society is now very dependent on electric energy because without the existence of electrical energy the community activity will be stalled. The loads used in electric energy operations vary widely. Electrical energy operations are severely disrupted due to unbalanced load and nonlinear loads. Unbalanced load and nonlinear loads used for the operation of electrical energy can be disturbing because they produce non-pure sinusoidal waves. THD_i (harmonics) caused by the unbalance of load and nonlinear load have an impact on electric energy losses and heat on the transformer. THD_i (harmonics) is caused by unbalance of load and nonlinear load Between Phases RN equal to 7.87%, at SN equal to 3.22%, and at TN 2,41%. After the Passive Filter design is installed THD_i between Phases becomes smaller that is at RN becomes 1.82%, SN becomes 0.82%, and in TN becomes 0.57%. THD_i (harmonics) between phases can be decreased by 76% after Passive Filter is installed. Desain Passive filters are very effective at reducing THD_i (harmonics) in buildings such as laboratories that use the load of imbalances and nonlinear loads for lab.
