This activity involves performing Insulation Resistance (IR) Testing on a 1000 kVA, 33 kV transformer and a 33 kV, 3-core 50 sqmm armoured cable using a calibrated insulation resistance tester (Megger).

The objective of this testing is to evaluate the condition of the insulation system, ensuring that the equipment meets safety standards, operates reliably, and is fit for safe energization and service.

For the transformer, insulation resistance measurements are conducted between windings (HV–LV, HV–Earth, and LV–Earth) to verify the integrity and condition of the insulation system.

Test results are recorded in megaohms (MΩ) or gigaohms (GΩ), where higher resistance values indicate a healthy insulation condition. All testing procedures are carried out in accordance with established standards, and proper discharge protocols are strictly observed after each test to ensure personnel and equipment safety.

The results obtained confirmed satisfactory insulation performance across both the transformer and the cable system, demonstrating their readiness for safe and reliable operation. This successful outcome not only reinforces system integrity but also adds significant value to the project execution.
