Load break swicth maintenance procedure...

Answer / Rajeev Ranjan Jha

The maintenance of a load break switch (LBS) involves periodic inspections and scheduled preventive maintenance tasks. Here's a brief list of steps:

1. Visual Inspection: Check for any signs of physical damage, corrosion, or wear and tear on the LBS components.

2. Cleaning: Remove dirt, debris, or other foreign materials from the load break switch and its surroundings.

3. Electrical Tests: Perform routine electrical tests such as continuity checks, insulation resistance tests, and dielectric loss factor measurements.

4. Mechanical Maintenance: Check and lubricate moving parts like bushings, bearings, and joints.

5. Insulation Resistance Test (IRT): Measure the insulating capacity of the switch contacts to ground.

6. Load Testing: Perform load tests to ensure that the LBS can safely handle its rated current and voltage under load conditions.

7. Preventive Maintenance: Follow a regular maintenance schedule to ensure timely replacement of parts like breather elements, ventilators, and pressure relief valves.
