Patent ID: 10928436

Abstract:
Embodiments of the disclosure are to evaluation of a phase-resolved partial electrical discharge (PD) of equipment insulation. In one embodiment, a method includes providing Phiqn-arrays by a measurement device configured to detect a PD process in electrical equipment. The electrical equipment can include high voltage insulation. The method further includes associating, by an equipment controller communicatively coupled to the measurement device, at least one Phiqn-pattern present in the Phiqn-arrays with a geometrical shape. The method also includes tracking, by the equipment controller, parameters of the geometrical shape in the Phiqn-arrays. The method also includes determining, by the equipment controller and based on the parameters of the geometrical shape, a discharge intensity associated with the Phiqn-pattern. The method may further include providing, by the equipment controller and based on the discharge intensity, a signal indicative of a condition of the high voltage insulation.
