ISBN: 9783659352362 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The simulated arc discharge is generated using high voltage power source in two round shape steel electrodes having 5 mm gap. This distance (between the sensor and arc discharge source) is set at 5 cm. The infrared thermometer (laser gun) was used to capture the insulation oil temperature by sending a laser light toward the insulation oil and that light will be reflected beck and received by the device and then the temperature of the oil will be captured and measured. This study will help to predict the insulation oil age of high voltage transformers, which reduce the maintenance cost of high...
