Check the listing for details. Two-channel discharge detection Local RF Transformer. Condition: New. Listed at 318.00 USD. The office release signal detects the RF module Partial discharge refers to the discharge between the electrodes but not through the electrodes, which is due to the existence of weak current in the insulation of the equipment or defects caused by the production process, and the phenomenon of repeated breakdown and extinction under the action of high electric field strength. It is manifested as the breakdown of the gas in the insulation, the local breakdown of the solid or liquid medium in a small range, or the local breakdown and discharge caused by the concentration of field intensity at the edge and sharp corner of the metal surface. The energy of this discharge is very small, so its short-term existence does not affect the insulation strength of electrical equipment. However, if the insulation of the electrical equipment continues to appear partial discharge under the operating voltage, these weak discharges will have a cumulative effect that will gradually degrade the dielectric properties of the insulation and expand the local defects, and finally lead to the breakdown of the entire insulation. 1.
