In this episode, we speak with OMICRON product managers Andreas Nenning and Lukas Klingenschmid about portable high-voltage power sources used for energizing electrical assets during off-line testing. They highlight available OMICRON solutions and what should be considered based on the testing application. In particular, they discuss the development and particular advantages of OMICRON’s 70 kV power source for off-line testing on air and gas-insulated switchgear among other electrical assets.
