Hot maintenance refers to the process of performing repair, maintenance, or upgrading of live electrical systems without de-energizing them.
Hot maintenance is critical for maintaining continuous power supply, minimizing outages, and ensuring reliability in the power distribution network.
This technique allows work to be done safely on live high-voltage lines or equipment.
Tools Used in Hot Maintenance:–
1) Insulated Gloves and Clothing: Specially designed to protect workers from high-voltage exposure.
2) Hot Sticks: Long insulated poles used to handle live electrical components from a distance.
3) Voltage Detectors: Devices used to detect live electrical lines and ensure safe working conditions.
4) Insulating Blankets and Covers: Used to shield nearby energized equipment or lines to prevent accidental contact.
5) Line Hose: Insulated hose placed over conductors to insulate and protect workers.
6) Aerial Lift Trucks (Bucket Trucks): Provide access to high-voltage lines while maintaining a safe working distance.
7)Harnesses and Safety Gear: Ensures that workers are securely fastened when working at heights
