Abstract

Listrik merupakan kebutuhan energi utama yang banyak digunakan dalam berbagai hal. Penggunaan energi listrik terus menerus memiliki tingkat resiko bahaya yang lebh tinggi oleh karena itu dibutuhkanlah sebuat sistem proteksi untuk mencegah resiko bahaya yang dapat merusak alat atau bahkan manusia. Penelitian ini memiliki tujuan sebagai berikut 1). Menjelaskan secara singkat mengenai sistem proteksi, 2). Menjelaskan sistem proteksi pada switchgear, 3). Menjelaskan komponen switchgear beserta fungsinya, 4). Menjelaskan bagaimana cara perawatan dari switchgear. Metode penelitian ini dilakukan dengan cara observasi, menganalisis, implementasi dan evaluasi. Sistem proteksi switchgear ini mampu berjalan apabila hanya terjadi permasalahan yang melebihi batas nilai yang terpasang.

Abstract

Electricity is one of the vital needs that is indispensable for all humans and other places, one of which is PT. Cemindo Gemilang, engaged in the cement-producing industry, requires a huge electricity capacity. To reduce or reduce the cost of electrical energy, a power plant unit and a WHRS (waste heats recovery system) were made to supply electrical energy to the cement plant area. PT. Cemindo Gemilang and the Power Plant rely heavily on electric motors, almost all of which operate using electric motors. The electric motor is a single-phase or three-phase type with a voltage of 11 KV, 6.6 KV or 400 volts. When all generating units operate, all electric motors that play an essential role will continue to be active so that damage is often caused by operation and service life therefore in the power plant department, and there is an electrical and mechanical maintenance division to maintain the continuity of the power plant operational system. This study's aim 1). Explain about electric motors, 2). Explain the definition of the water jet pump, 3). Explain how the water jet pump works 4). Explain the components used in electric motors and their repair and maintenance.
