The BDV (Breakdown Voltage) test and the Hi-Pot (High Potential) test serve different purposes in evaluating industrial oils. The BDV test primarily measures the dielectric strength of insulating oils, indicating their ability to withstand electrical stress before breakdown occurs, which is crucial for maintaining electrical equipment reliability. Conversely, the Hi-Pot test assesses the insulation quality of electrical apparatus by applying a high-voltage supply to identify potential insulation failures or breakdowns, ensuring safety and performance in operational environments. While both tests involve high voltage, the BDV test focuses on the oil itself and its electrical properties, whereas the Hi-Pot test evaluates the overall insulation system of equipment.
