Abstract
A testing arrangement for testing the dielectric strength of liquid insulating media has a test cell comprising an interior space for receiving the insulating medium to be tested and a first test electrode and a second test electrode for generating an electric field in a test volume of the test cell. The test cell is arranged in the interior of a receiving vessel which is filled with an auxiliary insulating medium or in the interior of an evacuated receiving vessel.

A testing arrangement for testing the dielectric strength of liquid insulating media comprising:
- a test cell having an interior space for receiving an insulating medium to be tested;
- said test cell having a first test electrode and a second test electrode for generating an electric field in a test volume of the test cell, said test cell having further a test cell base body with an inner wall surface delimiting the interior space of the test cell and with an outer wall surface, the test cell base body being made of an insulating material and having opposing first and second receiving openings through which the first and second electrodes penetrate;
- and
- said test cell being arranged in an interior space of a receiving vessel, the interior space of the receiving vessel in which the test cell is arrange being filled with an auxiliary insulating medium or being evacuated so that the outer wall surface of the test cell base body is subjected to the auxiliary insulating medium or to vacuum.
