Penelitian ini mempelajari pengaruh rongga udara (void) dalam isolasi epoxy resin terhadap karakteristik partial discharge (PD). Pengujian dilakukan pada sampel epoxy resin multilayer dengan ketebalan masing-masing lembaran ±0,35 mm dan ketebalan total ±1,05 mm dimana pada bagian tengah sampel diberikan artificial void masing-masing lembar sampel, dengan volume void total 27,49mm3. Tegangan t…
In the power system of the Bukit Siguntang Substation, specifically on the Rusa feeder, there is a protection system consisting of an Overcurrent Relay and a Groundfault Relay. Therefore, research was conducted on the evaluation of the coordination settings of the OCR and GFR protection system to maximize the performance of a selective and reliable protection system. Based on the value of the i…
This study aims to determine the effect of adding a flat mirror reflector to a 100 WP monocrystalline solar panel in its utilization as an energy source in a water lifting system by a 12 volt DC water pump engine with a power of 180 watts. This research was conducted for 14 consecutive days to collect data in the form of panel voltage and also DC water pump discharge by paying attention to weat…
This study aims to analyze the effect of load variation on the temperature of a three-phase induction motor operating in generator mode. Load variation is a critical factor as it affects power output and causes temperature changes in the motor. In this study, temperature measurements were conducted at various load levels, from 0 to 1000 watts, to observe the temperature rise with increasing loa…
Accidents can occur due to several factors, one of which is the human factor. One of the means of devices that plays a big role in safety when driving is braking. In addition to the need for safety in the form of braking, mileage is also a problem in the operation of electric vehicles due to the low capacity of the battery installed in the vehicle. Generally, braking is done mechanically, but t…
Motor control is a broad trem that means anything from a simple toggle switch to a complex system with components such as relays, timer, and switches. the common fuction of all controls, however, is to control the operation of an electric motor. as a result, when motor control equipment is selected and installed, many factors must be considered to ensure that the control
Electric Motors and motor control, 2nd edition, is intended to help student electrician, and practicing electricians learn how motor operate and how to instal them. the book helps students understand how control are designed and installed to provide either simple or complex control schemes
Tranformator merupakan alat listrik yang memiliki fungsi sebagai pemindah energi dengan prinsip induksi elektromagnetik.. Sebagian besarmminyak isolasi yang digunakan pada Transformator berasal dari minyak bumi yang tidak terbarukan. Maka dari itu dibutuhkannya alternatif minyak isolasi dengan tingkat biodegradabilitas tinggi. Minyak nabati yang dirasa cocok untuk diteliti sebagai minyak isolas…
