Capacitance testing measures the insulation’s ability to store electrical energy between the bushing’s conductive core and the grounded transformer tank. The test is conducted by applying a voltage to the bushing and measuring the current flow through the insulation. Changes in capacitance values over time can indicate insulation deterioration, helping identify potential issues before they lead to failure.
