Stationary Inspection of Components in the field of eMobility – ISOTEST® act Industry Solution

Contrary to conventional cars, battery cells are used as energy source in electric vehicles. Due to the high storage requirement, a multitude of cells that are connected to electrical busbars is used. Different coating methods, such as those with epoxy, guarantee the enormous demands on the insulation class.


The most diverse coatings are material-friendly tested for pores, cracks and other damage with the stationary ISOTEST® act in-plant holiday detector system.
In combination with robotic systems and tailor-made accessories a fully automated testing can be done.


Renowned car manufacturer rely on the ISOTEST® act.

Our recommendation

In-plant Holiday Detector ISOTEST® act 8.0 / 35

  • test voltage 0.5 - 8.0 kV, 0.5 kV steps (ISOTEST® act 8.0)
    or 7.5 - 35 kV, 2.5 kV steps (ISOTEST® act 35)
  • high-voltage pulse technology
  • no static charging
  • testing of dirty, damp and even slightly conductive surfaces
  • up to 6 test channels – synchronisation of several devices (master / slave mode)
  • “Phantom-Grounding” – no direct grounding necessary
  • external switch-on / switch-off of the test voltage
  • adjustable sensitivity and filter functions
