The dielectric strength of transformer oil is a crucial parameter that indicates the oil’s ability to withstand electrical stress without breaking down. Transformer oil typically has a high dielectric strength, often ranging from 30 kV/cm to 70 kV/cm, depending on its purity and condition. This property is vital for ensuring the safe operation of transformers, as higher dielectric strength minimizes the risk of electrical discharge and enhances the insulation performance. To accurately measure this property, a transformer oil BDV testing machine is used, which provides precise readings to assess the oil’s insulation capability and detect any deterioration or contamination that could affect the transformer’s performance. Testing should be conducted regularly to maintain the effectiveness of the transformer oil and ensure operational reliability.
