A "transformer dielectric strength test" is a type of electrical test conducted to assess the insulating properties of a transformer's dielectric materials, such as the oil or other insulating fluids used in the transformer. The primary goal of this test is to ensure the safety and reliability of the transformer by confirming that its insulation can withstand the stresses of normal operation and potential transient voltage spikes without breaking down.
Here's how the transformer dielectric strength test works and how it ensures safety:
Dielectric Strength Test Process:
Preparation: The transformer is filled with insulating oil or fluid, which is used to immerse the components being tested.
Electrodes: Two electrodes, typically in the form of flat metal plates
