PENGARUH PUTARAN MOTOR INDUKSI PADA GENERATOR LISTRIK YANG DIGERAKKAN TURBIN UAP PROTECTED DITINJAU BERDASARKAN KARAKTERISTIK GETARAN DAN TIME DOMAIN

Abstract

Study of vibration characteristics of an induction motor that is not controlled and is not closely monitored and regularly adversely affects the vibration and the impact on comfort and engine life. This study aims to investigate the characteristics of vibration on electric-driven generator steam turbine at Limited Liability Perkebunan Nusantara III (PTPN III) Rambutan Tebing Tinggi. The object of research is protected steam turbine engine Palm Oil Processing Factory Company Limited Perkebunan Nusantara III Rambutan Tebing Tinggi. The results of this study show from both the point of measurement at engine speed rpm compared 4800, 4900, and 5000 obtain that the vibration velocity is highest at 120 seconds, 5000 rpm rotation Vertical direction at the point G1.Dari ISO 10816-3 standard for velocity on the highest vibration response measurements at two measurement points on the position of the engine cradle generator of 0.650 x 10-6 m / s Zone A is green, the vibration of the engine is very good and below the allowable vibration.
