Figure 7a shows RMS values of EAF currents during one heat cycle that includes three heating periods for the steel recharging or tapping (draining liquid steel) the furnace. Three periods of current interruptions are intentional and are required for the steel recharging. Figure 7b shows minimum and maximum current values to better depict chaotic current changes. Currents rapidly change from low values to over 90 kA — back and forth. (a) RMS Values (b) Max and Min Values Fig. 7: EAF Currents during one Heat Cycle (current values averaged during one second) 49 Actual Trends in Development of Power System Protection and Automation In summary, the following challenges exist to design reliable differential protection for EAF transformers.

These relays can accept two different types of analog input boards — the first for connection to conventional current transformers and the second for Rogowski Coils. Idea relays use the ProView operating software package designed for PCs running the Microsoft® Windows® operating system. The Idea Workbench feature of the ProView software allows the user to customize the protection and control function logic. Typical protection schemes include line protection, transformer differential protection, rotating machine protection, bus differential protection, capacitor bank protection, and series and shunt reactor protection.
