Abstract

Nilai pecahan pada bahasa mesin tidak dapat diimplementasikan, dikarenakan bahasa mesin hanya mengenal bilangan biner. Untuk bisa mengimplentasikan nilai pecahan pada bahasa mesin, perlu pemodelan dan pemisalan. Setelah nilai pecahan dimodelkan dan dimisalkan, nilai tersebut diubah menjadi bilangan biner. Pada bilangan biner yang telah dimodelkan dan dimisalkan, dapat dilakukan semua operasi aritmatika. Untuk mengetahui nilai sebenarnya, maka nilai biner hasil operasi aritmatika perlu dikembalikan lagi kebentuk tanpa pemodelan dan pemisalan.

Abstract

This study examines the insulation resistance of underground conductors connecting 3-phase induction motors that drive pump machines. The results of the insulation resistance measurements were analyzed using the Polarization Index (PI) method and the Dielectric Absorption Ratio (DAR) method. There are 3 areas of conductor cables analyzed to calculate the remaining life of each conductor cable. For area 1, the remaining life of the inter-phase conductor cable is R-S 20.9 years, S-T 20.5 years T-R 20.8 years. Area 2, the remaining life of the inter-phase conductor cable is R-S 20.6 years, S-T 20.7 years T-R 21.1 years. For area 3, the remaining life of the inter-phase conductor cable is R-S 16.5 years, S-T 14 years T-R 15 years.
