Measurement of shield currents in electric vehicles

New application example

Read in our new application example how shield currents can be measured easily and safely.

High-voltage electrical systems in electric vehicles are becoming more and more extensive due to the large number of included consumers. Not only the connected components have to be extensively tested and optimised, but also the HV cables have to undergo thorough tests. Occurring shield currents can lead to cable fires and damage to components and must be measured and verified simultaneously in all circuits.

The development of high-performance electric passenger cars, commercial vehicles, buses or mobile machines poses extraordinary challenges due to a particularly large high-voltage vehicle electrical system. High shield currents can destroy the cables and must be measured.
