How earth fault in DC circuit will affect my control system?
how safe is my system if i use DC supply ( 220 V)insteadof AC supply(240 V AC)?.
i am planning to set a system to control and monitor steam generator pressure. which supply i should go far?
Neither is inherently safer than the other. As for monitoring, pressure transducers typically operate at low voltages, 5-36V DC. You do not describe how you will regulate pressure.
I work with hydraulics but the principle is the same.
