This test is done with the initial transformer design to validate the integrity of the insulation and its high frequency surge withstand capability.
Witryna22 cze 2024 · Example for diagram above: a lightning impulse withstand voltage of Up = 120 kV is required at an altitude of 1800 m. A system with a rated voltage of 36 kV achieves this, while a 24 kV system is not suitable because it can only maintain a lightning impulse withstand voltage of 125 kV up to 1000 m. Witryna24 mar 2024 · Fig. 12: Lightning impulse withstand of sheath interrupts and cable jacket. Switching surge impulse withstand of the sheath interrupt and jacket are assumed to be similar to other insulator types and are 83% of the lightning impulse withstand rating (BIL).
