    460/220V Delta Transformer

    Busbar, you are obviously a man of vast experience as you have your priorities set(in my view)correctly! Although fishing isn't my preferred recreational activity, I can appreciate the importance of recreational libations being readily available at the bait shop. Just one query from your last...

    460/220V Delta Transformer

    Thanks for the replies everyone. I should have supplied more background information originally. For Ausphil... The application is at a US based manufacturing plant where the main distribution is a 460V. Transformers are then used to supply loads such as lighting and GPO's at other voltages. As...

    PID algorithm - determining coefficients

    Gaby, to write one algorithm to adequately perform your control task is quite a mission! The best approach is to separate the control tasks - one to perform the PID control at the given setpoint and one to provide the setpoint to the PID control (eg. to ramp the setpoint from 20deg to 250 deg...

    460/220V Delta Transformer

    G'day Everyone, Please excuse my ignorance (hey, I'm from New Zealand!) but I would like to know why you would select an unearthed 3-phase supply from a transformer(eg. 460/220V delta)over a wye-connected supply with an earthed neutral. The particular example I'm looking at is a transformer to...
