Timeline
- 00:00:00 - 00:06:42
The video begins with an introduction to the laboratory focused on the distribution and utilization of electrical energy, specifically detailing the practical module on transformer testing. The process starts with shutting down the transformer and opening all doors for ventilation to release heat. The temperature of the room and transformer is measured using a thermovision device, showing a temperature of 42.0 degrees Celsius. Once the temperature is deemed cool enough, insulation resistance testing is conducted using an insulation tester that injects a voltage of 5,000 volts. The setup involves connecting the tester's probes to the transformer, ensuring safety with 20 kV gloves. The tester is set to 5,000 volts for a duration of 10 minutes, with results recorded at 1.20 and 1.03 during different tests. After completing the insulation resistance measurements, the equipment is turned off, and the area is cleaned up. The session concludes with a summary of the practical work done, emphasizing the importance of safety and proper procedure in electrical testing.
