    Controller for Power Substation

    Hello everyone, I am looking for a controller (PLC-like) for a power substation. It must have: 1.- analog input for three phase current (5A) and voltaje (120V), coming from substation current and voltaje transformers, as most protective relaying equipment has. 2.- 4-20 mA analog input (PT100...

    Transformer aging v/s high current faults

    Hello everyone. Currently, we are feeding a distribution network (13.8 kV) through a 33 MVA 110/13.8 kV transformer. Due to the high magnitud of the line short circuit current in the 13.8 kV network (about 8kA), we are looking for a relationship between transformer aging and -for example- the...

    remote terminal voltage - transmission line

    Hello Everyone, We are developing some control applications in the local terminal of a 110 kV transmission line. The control requires to know the voltage in the remote terminal of the transmission line. We need to compute (or estimate) that remote terminal voltage, as we d like to avoid the...
