Electrical Safety - a Hot Topic
The pots in smelting systems in which the metal is melted are operated with various voltages and currents. The supply is often ungrounded. 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 Power Distribution
Safe Power for Reliable Results
The power supply is critical to refining and smelting systems. The medium voltage supplied to the facility is transformed down to 480 V or 600 V and distributed through the facility via electrical cables or busbars often referred to as branch feeders. It is then either connected to loads or transformed to lower voltages. Depending on the system grounding either a Bender ISOMETER®s or RCMS residual current monitoring relays (ground-fault monitors) monitor these and help ensure continuous operation. Fault detection is only the first step in troubleshooting. The addition of downstream monitors and current sensors can allow quicker and safer location of ground faults. References mention that approximately 80-95% of the faults in a facility start as a phase-to-ground fault – making this time savings compound the return of investment.
