How to Perform Insulation Resistance Test of a 33 kV Lightning Arrester | Megger Test Procedure

In this video, we demonstrate how to perform an Insulation Resistance (IR) Test of a 33 kV Lightning Arrester using a Megger insulation tester. This test is an important part of substation maintenance and high-voltage equipment testing.
You will learn:
What is a Lightning Arrester (LA)
Why Insulation Resistance Testing is important
Step-by-step procedure to test a 33 kV Lightning Arrester
Correct Megger voltage selection (1000V / 5kV)
How to interpret the IR test values
Regular IR testing helps ensure the reliability and safety of power system equipment and prevents insulation failure in substations.
This video is useful for electrical engineers, technicians, solar plant O&M engineers, and students working in the power sector.
