JEAN MÜLLER provides its customers in the low-voltage power distribution sector with components and systems featuring a new generation of measuring electronics that can withstand high-voltage tests as part of maintenance tasks.

Due to the legal requirement for recording energy data in the supply network, measuring electronics are increasingly being used in NH fuse-switch disconnectors. These are operated at a low voltage range up to 24 V, which is in conflict with the performance of routine maintenance tasks with voltages up to 5,000 V, such as cable fault location. This dilemma has now been resolved with the new generation of measurement electronics from JEAN MÜLLER.

“Until now, it was not possible to use measuring electronics in the low-voltage range and carry out the necessary high-voltage tests as part of cable fault location without destroying the measurement electronics,” says Torsten Wolf, Senior Product Manager at JEAN MÜLLER. “With the new generation of measuring electronics for our NH fuse-switch disconnectors, we have succeeded in resolving this conflict. This enables our customers to meet the requirements of smart grids and reconcile this with the usual maintenance tasks.”
