Abstrak
The operation of non-linear load are causing harmonic. The level of distortion or called Total Harmonic Distortion (THD) is high potential to degrade the quality of electrical energy is distributed. In this study was conducted measurement of the THD at each Sub Distribution Panel (SDP) in Klungkung Hospital. The results of the initial measurements indicate the highest ITHD value contained in the SDP P.AC amounted to 45.73% and the lowest is 3.93% at SDP UGD. While the value of the initial measurement result VTHD an average of 5.3%. Referenced standard is IEEE Standard 519-2014, wherein ITHD standard limit is 8.0%, and the standard limit of VTHD is 8.0%. THD value which passed the standard is analyzed and simulated in software ETAP with the addition of a damped filter to reduce the value of THD which passed the standard. Based on the simulation results after the addition of a damped filter, ITHD value has decreased in each of the SDP. However, only a few SDP with ITHD in accordance with the standard. The decrease ITHD highest is 10.63% at SDP P.AC, and the lowest is 2% at SDP IPSRS. VTHD value at each SDP after the addition of a damped filter also decreased with an average decrease of 1.74%.
