After the installment of passive filter of 3 steps, the data of % thd current is R = 2,7 %, S = 2,1 %, T = 3,6 %. For % THD the voltage is shell under standart. The result of the research for % THD current for each phase before the passive filter installed is R = 15,9 %, S = 10,9 %, T = 12,1 % for available data of % THD current over IEEE 519 – 1992 of 5 %. The objective of the discussion is to reduce the harmonic caused by economic electrical energy by using the passive electrical filter. The effect is on the damage of electrical equipment such as generator, electrical motor, transmition and transformer. As the frequency of voltage source i.e 50 Hz, it will cause the distorted wave resulting at the damage of amplitude wave of power system.

Kata-kata kunci: Harmonisa, frekuensi, distorsi, amplitudo Abstract The harmonic is the phenomenon of sinus wave deviation caused by the use of electrical energy load of semi conductor devices such as economic electrical energy, TV, printer, and computer. Dari data ini % THD untuk arus harmonisa telah tereduksi hingga di bawah standar IEEE 519-1992 yakni sebesar 5 % dengan menggunakan filter pasif.

Setelah pemasangan filter pasif pada step 3 data % THD arus diperoleh R = 2.7 %, S = 2.1 %, T = 3.6 %. Untuk % THD tegangannya masih di bawah standar. Dari pengujian yang dilakukan untuk % THD arus, diperoleh hasil pada masing-masing fasa sebelum filter pasif terpasang sebesar R = 15,9 %, S = 10,9 %, T = 12,1 % dari data pengukuran yang ada % THD arus melebihi standar IEEE 519-1992 sebesar 5 %.

Tujuan pembahasan yaitu menekan atau mereduksi harmonisa yang ditimbulkan oleh lampu hemat energi dengan menggunakan rangkaian filter pasif. Karena frekuensi gelombang harmonisa tidak sama dengan frekuensi sumber tegangan yaitu 50 Hz, maka akan menimbulkan gelombang yang terdistorsi yaitu cacatnya gelombang amplitudo suatu sistem tenaga listrik, dampaknya terjadi kerugian pada peralatan-peralatan listrik lainnya seperti generaror, motor listrik, saluran transmisi dan transformator. Abstrak Harmonisa merupakan suatu gejala gelombang sinus yang timbul akibat pemakaian energi listrik dengan beban berupa peralatan semikonduktor seperti lampu hemat energi, TV, printer, komputer dll. It produces very nice visual effects and simultaneously provides an effective observable way to. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways. You can embed this unit in an audio system or use it as a stand-alone unit. Color ( 80, 0, 120 ) uint32_t ro = pixels. This is a real time LED Audio Spectrum Analyzer. Color ( 0, 0, 0 ) uint32_t gr = pixels.
