The BIL test, or Basic Impulse Level test, for transformers is a critical diagnostic procedure aimed at assessing the insulation strength of transformer windings and components under high-voltage conditions. This test simulates lightning and switching impulses to ensure that the transformer’s insulation can withstand electrical surges without failure. By applying standardized impulse voltages, it evaluates the robustness of the insulating materials used in transformers, which is essential for ensuring long-term operational reliability and safety. Proper testing with the right equipment, such as those from Globecore, guarantees that a transformer can handle unexpected voltage spikes, ultimately protecting the equipment and extending its lifespan. For accurate measurements and diagnostics, utilizing a bil test transformer is essential to verify insulation integrity.
