"Pada penulisan tugas akhir ini membahas mengenai pengujian transformator dan bagaimana pengaruh suhu saat transformator diuji dan untuk mengetahui beberapa spesifikasi dan karakteristik dari inti trafo tersebut. PLN Pusat Penelitian dan Pengembangan (Puslitbang) sebagai jaringan dan wadah untuk melakukan pengujian di beberapa alat listrik sebagai persyaratan awal suatu alat dipakai dalam sistem tenaga listrik yang dipakai oleh PLN. Pengujian yang dilakukan di PLN Pusat Penelitian dan Pengembangan (Puslitbang) ialah pengujian tanpa beban dan pengujian berbeban. Fokus dari penelitian kali ini ialah untuk menunjukkan korelasi antara temperatur dengan besar resistansi pada belitan. Akan dipaparkan proses pengukuran yang dilakukan serta beberapa standar yang dipersiapkan sesuai dengan standar yang dipakai oleh Laboratorium Hubung Singkat Puslitbang. Disertai juga dalam bentuk grafik dalam pembuktian korelasi dalam bentuk grafik. Dipaparkan pula besar energi panas yang dilepaskan saat pengujian berbeban. Dengan besar energi panas yang dihasilkan selama pengujian akan ditemukan besar kenaikan temperatur yang terjadi.

At this study, it discusses about some of test on power transoformerhow the effects of the and for acknowledge several specifications and characteristics of the transformer core. PLN Research and Development Center (Research) as the container for testing the network and perform testing in some electrical appliance as an initial requirement of a tool used in the electric power system used by PLN. Tests conducted at PLN Research and Development Center (Research) is the noload testing and load testing. The focus of the present study was to demonstrate the correlation between the temperature with a resistance winding. It will be present the measurement process with some standards that are prepared in accordance with the standards used by the Laboratory Center for Short-circuit. Accompanied also in graphic form in proving the correlation in graphic form. It?s also present the heat energy released when load-loass test with a large rise in temperature occurs."

"Electric motors and drives : fundamentals, types and applications provides information regarding the inner workings of motor and drive system. The book is comprised of nine chapters that cover several aspects and types of motor and drive systems. Chapter 1 discusses electric motors, and Chapter 2 deals with power electronic converters for motor drives. Chapter 3 covers the conventional d.c. motors, while Chapter 4 tackles inductions motors – rotating field, slip, and torque. The book also talks about the operating characteristics of induction motors, and then deals with the inverter-fed induction motor drives. The stepping motor systems; the synchronous, switched reluctance, and brushless d.c. drives; and the motor/drive selection are also covered. The text will be of great use to individuals who wish to familiarize themselves with motor and drive systems."
