A new test equipment for partial discharge measurement in stress relief cone

摘要

The present invention relates to a structure of a test apparatus for evaluating the actual junction box assembly condition and the electrical properties of the stress cone by the partial discharge measurement generated around the stress relief cone, using a quality check test equipment of the stress cone having the same field .; Partial discharge test device of the stress cone is an electrical signal that is, a partial discharge generated in the coupling part in the standing stress cone so designed to equalization is similar to that applied to the stress relief cone in the present and potential equalization is applied to the actual connecting compartment stress cone invention so you can check the quality by measuring the stress cone may be aware of the defects of the stress cone in advance.
