Arus yang besar akan menghasilkan panas yang besar pula, panas ini dapat merusak motor itu sendiri dan tujuan penelitian ini agar dapat mencari metode pengasutan yang tepat untuk mengurangi arus start yang besar pada motor. Pengasutan pada motor induksi 3 fasa mempunyai beberapa metode yaitu Direct On Line (DOL), star-delta, auto trafo dan soft starter. Untuk dapat mengetahui arus kutanga mota dapat menggunakan metode simulasi dengan software ETAP Power Station. Dari hasil simulasi yang dilakukan ETAP didapatkan hasil sebagai berikut, untuk metode pengasutan direct on line (DOL) diperoleh arus start sebesar 2807,9 A kana 5,25 kali arus nominal nevoltage dip pada 14,88, sebesar1039,2%. Untuk metode star-delta diperoleh arus start 2,12 A kana 5,51 kali arus nominal uye voltage dip pada bus sebesar 790,2%. Untuk metode auto trafo diperoleh arus start sebesar 1,61 A kana 4,19 kali arus nominal uye voltage dip kuita XNUMX%.
