Abstract

Permintaan beban yang semakin meningkat dapat menyebabkan daya listrik juga semakin besar. Jika transformator daya bekerja pada kondisi overload dan berada diatas titik panas, maka mempercepat terjadinya penuaan dan kegagalan pada minyak isolasi transformator. Penerapan distributed generation (DG) dapat memberikan supply daya listrik tambahan ke beban (rumah tangga). Sehingga dapat meringankan beban kerja transformator daya dan mengurangi percepatan penuaan minyak isolasi transformator. Penelitian ini menganalisis pengaruh pembebanan dengan injeksi DG pada distribusi listrik 20 kV dengan sistem 150/ 20kV terhadap arus, rugi-rugi sistem jaringan, dan kondisi minyak isolasi dengan menggunakan software ETAP. Pengujian dilakukan pada kondisi pembebanan selama 24 jam pada sistem distribusi. Perhitungan temperatur minyak isolasi dilakukan menggunakan rumusan matematis sesuai standar IEEE, kemudian kekuatan dielektrik isolasi minyak diuji dengan breakdown voltage (BDV) test menggunakan standard SPLN 49-1 dengan metode uji IEC 156. Sehingga penelitian ini dapat mengidentifikasi kondisi minyak isolasi transformator berdasarkan kapasitas pembebanan dan nilai tegangan tembus minyak transformator. ================================================================================================= Increasing the demand for loads can causes the greater of eletrical power needed. When the transformer operation in overload conditions and hot-spot temperature,accelerate the aging and failure inoil insulation of transformer. Applicationof distributed generation (DG) providesthe additional of electrical power supply to the loads (household). So that, it can relieve the workload of power transformer and reducethe acceleration of aging in oil insulationof transformer.This research analyse the effect of loadingcapacity with DG injection oncurrent flow, losses, andcondition of oil insulation on20 kV of electricity distribution, 150/ 20kV system using ETAP software. Tests of this research carried out on 24 hour of loading conditions ondistribution system. The calculation of isolation oil temperature carried out using a mathematical formula according to the IEEE, andoil insulation tested with a breakdown voltage (BDV) testbased on standard of SPLN 49-1 and using test method of IEC 156. Thus,research expected to identify the transformer insulation oil condition based on loading capacity and breakdown voltage value of transformer oil insulation.
