Hi, I am an Electrical Engineer with roughly 12 years of experience working in various industries designing systems and circuits, especially for large scale production machines and lifting equipment (e.g. Container cranes, high speed cutters, yarn rewinders etc.). Among these I have made voltage and current sensing circuits numerous times. I have a few questions regarding the project, such as have you decided on the components to use, such as CTs and PTs etc.? If not I can certainly aid with that. A more fundamental question is whether you want to even go the CT route for the current sensing, or maybe just shunt resistors? Please, let's discuss these in the chat. Regards, Safi
