In some South-European countries DSOs in the process of substation automation are procuring separate 24V dc power supplies for supply of RTU and comm equipment, while existing 24V or 110V dc systems are used for new IEDs and other substation primary equipment?
What are advantages and drawbacks of having two separate dc systems in one station?
Many thanks in advance.
