PHovnanian thanks for the reply. No it does not have any filters, it is just an off the shelf type A rcd. Looking into this further i am thinking of using a type B such as the siemens range. Hopefully this will work due to the ability to detect dc fault current component of the thyristor phase...
Hi Scotty UK please find attached a sketch of what i have @ the moment. The reason for 414v supply is that i have 12 of these altogether and so i am trying to balance out the load. PS the load current is approx...
I have an application that uses thyristor power controllers to heat up a "melting pot". The supply is 415v 2 phase that is fed through a stepdown transformer giving a secondary voltage of 240v centre tapped. This is fed to thyristor power controller which has a resistive load . If a wire is...
