Electrical safety - a hot topic

[] Schmelzanlagen

The pots in smelting systems in which the metal is melted are operated with various voltages and currents. The supply is often unearthed. In most systems, the pots must be monitored separately to avoid shutting down the whole plant in the event of a fault. The EDS fault location system is an excellent option here. It quickly and automatically locates defective power circuits.

Low-voltage distribution boards, feed-in

A safe power supply is the basis for reliable results

Low-voltage distribution boards

The power supply is decisively important when it comes to smelting systems. The medium voltage fed in is transformed down to 400 V in the transformer stations and fed to the system via cable bars or busbars and the low-voltage distribution board and sub-distribution boards. Bender ISOMETER®s or RCMS residual current monitoring systems monitor this and ensure continuous operation. Power quality drives are the perfect solution for monitoring the main and the sub-distribution boards.
