  • Effective and Safe Testing of GIS Switchgear -

    2 mins readGas-insulated switchgear (GIS) in particular poses unique and special challenges, including the connection of the test equipment. In today‘s world, where testing is increasingly performed in a non-invasive manner, test systems must offer a certain flexibility and a wide range of testing solutions in order to get proper results in a timely manner.

  • Testing Distribution Switchgear for Partial Discharge

    From extensive testing of switchgear with partial discharge tracking across the surface of insulation it has been observed that surface discharge activity often has low amplitude but very high discharge rate. An example of this can be seen in Fig.1 where surface discharge was occurring across the polymeric insulation of an 11kV circuit breaker.File Size: 345KB

    One more test you may want to do is to make sure your outlet is getting live power through the correct side of the socket. To do this, place the red lead in the socket on the middle of a 3-pronged outlet and place the black lead in the negative or ground socket on the left hand side. There should be no reading, or the reading should be zero.
