Summary: | An electric motor that is used continuously will experience a decline in performance and even be damaged, maintenance and repair of electric motors must be done based on standards so that all existing specifications can be met and repairs deserve to be accepted. Where in this case motor repair is done by overhauling, where overhaul is a comprehensive repair or maintenance activity by repairing or replacing parts of electric motors that are damaged. Based on visual data and electrical measurements the decrease in the value of the polarization index (PI) of the induction motor is caused by dirty and moist winding conditions. Overhaul is done in 8 stages, namely; planning, dismantling, electrical measurement, mechanical measurement, electrical action, mechanical action, assembling and noload test running. After overhauling, the result shows that the value of the polarization index (PI) increased by 1.4 from 1.8 to 3.2, which is above the standard value set by IEEE 43. Suatu motor listrik yang digunakan terus menerus akan mengalami penurunan performa bahkan rusak, perawatan dan perbaikan motor listrik harus dilakukan berdasarkan standar supaya semua spesifikasi yang ada dapat terpenuhi dan perbaikan layak untuk diterima. Dimana pada kasus ini perbaikan motor diakukan dengan cara overhaul, dimana overhaul merupakan kegiatan perbaikan atau perawatan secara menyeluruh dengan cara memperbaiki atau mengganti bagian dari motor listrik yang mengalami kerusakan. Berdasarkan data visual dan pengukuran elektrik penurunan nilai polarization index (PI) motor induksi disebabkan oleh kondisi winding yang kotor dan lembab. Overhaul dilakukan dengan 8 tahapan, yaitu; planning, dismantling, pengukuran elektrik, pengukuran mekanik, tindakan elektrik, tindakan mekanik, assembling dan running test no load. Setelah overhaul didapatkan hasil bahwa nilai polarization index (PI) meningkat sebesar 1.4 dari sebelumnya 1.8 menjadi 3.2, berada diatas nilai standar yang ditetapkan oleh IEEE 43. |
