Abstract

The invention discloses an apparatus, method and device for verifying a TEV (transient earth voltage) local discharge live detection device, wherein the apparatus comprises a pulse generator for transmitting a calibration signal; a coupling device connected with a metal plate of matching impedance through a coaxial RF cable, wherein a TEV sensor under test is attached to a predetermined position of the metal plate; and a TEV tester main unit for testing a pulse response signal, wherein results of comparison for the pulse signal and the calibration signal are used for indicating test performance of the TEV local discharge live detection device. The technical problem that the related part is unable to provide field verification for TEV local discharge live detection equipment is solved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a calibration device, method and device for a TEV partial discharge charging detection device. Background technique [0002] The survey shows that there is no scientific and effective on-site method for TEV partial discharge detection devices. Generally, a lighter is used to simply ignite near the RFCT. Effectively find a slight decline in system performance or perform quantitative evaluation. [0003] Aiming at the problem that the relevant technology cannot perform on-site verification of the TEV partial discharge electrification detection device, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of the present invention provide a verification device, method and device for a TEV partial discharge electrification detection device, to at least solve the technical problem that related technologies cannot perform on-site verification of ...
