Basically a heat exchanger is a heat transfer device used to transfer internal heat energy between two or more fluids available at different temperatures. In most heat exchangers, the fluids are separated by heat transfer surfaces, and ideally they do not mix. Heat exchangers are used in process, power, Petroleum, transportation, air conditioning, refigeration, cryogenics, heat recovery, altern…
Cyclone separator is a device for separating solid particles and fluids. There are several ways that can improve cyclone performance, one of which is modification by adding cyclone with a smaller geometry size to obtain more efficient performance. In this study, one cyclone with a smaller geometry was added to the main cyclone and used one type of particle, namely coconut shell powder. Where in…
Salah satu bagian yang terpenting dari transformator adalah minyak isolasi. Iasolasi cair yang biasa digunakan saat ini adalah minyak mineral. Dimana minyak mineral ini tingkat terurainya sangatlah rendah. Untuk itu perlu dilakukan penelitian lebih lanjut mengenai minyak isolasi berbahan minyak nabati yang ramah lingkungan. Minyak kelapa sawit RBDPO Olein salah satu minyak nabati yang kekuatan …
Pada umumnya, minyak bumi sering digunakan sebagai isolasi cair karena kinerjanya yang baik dan harganya yang relative murah. Namun minyak bumi yang memiliki sifat tidak dapat diperbarui jika digunakan terus menerus maka akan habis. Berbagai studi dan penelitian telah banyak dilakukan untuk mencari alternatif isolasi cair yang dapat diperbarui dan ramah lingkungan dimana minyak nabati dianggap …
Liquid isolation is one of the materials that is very useful for protecting both human and electrical components such as transformer from the danger of electricity. One of the liquid isolation is created from palm oil (RBDPO) that still need to be added titanium dioxide (TiO2). Before it become liquid isolation, it need to be tested, one of them is partial discharge testing. PD testing, in this…
