    HART Communication with DVC6200

    For this specific project i got a DVC6200 that i want to communicate through HART. I am using Scadapack 474 and the expansion 6602 for it has 4 AO. My question is can i feed 4-20 mA to DVC 6200 as loop power and get the signal back from positioner in HART to the 6602 AI?

    Sizing an NGR

    I am using a 4.16 kV to 25 kV transformer at 5.6 MVA, 7% impedance Del, wye for my project. I want to size an NGR for this transformer. Thing is, 25 kV is too high for my standards and this is the first time i am working on it. My initial calculation for NGR gives 130A Earth fault current and...

    MV Power plant

    Hey guys, Newbie eng here. Working on a powerplant design where we have 4 x2.5 MW, 4.16 kV generator and one backup generator which only operates when one of the 4 generator is down to achieve N-1 redundancy. Issue is i cant decide on which bus system to be used. Using a common bus seems more...
