タイムライン

00:00:00 - 00:05:00
The session begins with an introduction to the electrical distribution laboratory, focusing on testing and inspecting equipment used in electrical distribution installations. Various tools are introduced, including a VCB stick for activation/deactivation, a key for energizing, grounding equipment, and components like a micrometer for measuring contact resistance. Safety checks are emphasized, including verifying that there is no residual voltage present on the cubicle body before proceeding with the inspection.
00:05:00 - 00:10:00
After ensuring safety, the VCB's status is checked, and the cubicle is opened properly. The heavy-duty connectors are accessed and the PT (potential transformer) is carefully removed for testing. The micrometer is set up to measure contact resistance, using specific terminals to ensure accurate readings. The process involves adjusting the current to 100 amperes and observing the measurements obtained before safely reassembling the equipment.
00:10:00 - 00:19:23
The final steps involve reactivating the VCB, reassembling the setup carefully, and documenting the measured results. The cubicle is closed, grounding is safely disconnected, and the testing concludes with a final verification of the VCB's status, ensuring it is operational while maintaining safety procedures throughout the experiment. The session ends with a summary and thanks.
