System for monitoring the magnet yokes for earth faults

This system, which enables the monitoring of the magnet yokes, has been successfully established on the market for over 10 years now. With the help of this system, the operator or maintenance technician can locate the damaged area by an exclusion procedure. In this system each magnet yoke is insulated from the furnace housing. However, this function is still guaranteed with an earth leakage cable, which in turn is connected to the furnace housing.

This design enables the operator and maintenance staff to separate the affected magnet yoke quickly and purposefully by individually interrupting these earth fault connections. In this way, a costly and time-consuming retraction of the magnet yokes for fault fi nding can be avoided.

System for monitoring the molten bath

The molten bath earth monitoring is the most important safety system for foundries in a crucible furnace plant. With the help of our control technology, existing systems can be modernized and plants without a molten bath earth monitoring can be retrofi tted.

The following functions are checked:
  • Permanent insulation monitoring
  • Testing the connection of the bath antenna to the molten metal
  • Testing of an external earthing on the furnace system
  • Crucible breakage test
