    Static Exciter Field Cables

    Thank you all for the responses. I'm going to look into the field forcing capabilities of the excitation system and I'll post again with what we've decided to do.

    Static Exciter Field Cables

    I was recently told that the field cables for Static Excitation Systems need to be rated for 10 time (10x) the max exciter voltage… is that true?... is it in an IEEE Spec somewhere? For example, I’m spec’ing a cable a for a static exciter field run that will have 240 V (nominal) and 360 V...

    3V0 (broken delta) Resistor Sizing

    Great discussion everyone. Thanks for the help. CE

    3V0 (broken delta) Resistor Sizing

    The guide I had said to use this equation: Vresistor(max) = 3x(Vlg/VTR), where Vlg is Voltage (line to ground) of the primary and VTR is the turns ratio of the PTs. So in my case it would be 3 x (2402V/35) = 206V. But either way you bring up a good point… Do I need the resistor to begin with?

    3V0 (broken delta) Resistor Sizing

    Hello All, I have a 3V0 (broken delta) resistor sizing question… We have a 4160V, 1388kVA generator connected to a step-up transformer using a short distribution line (approx 3800 feet). The generator has a HRG system on it. The distribution line is at 4160V and is configured as an...

    PE Stamps

    Thanks for the postings everyone, they were very helpful. … and I am getting it… why do think I posted the question in the first place?... because it didn’t sound right to me either! Thanks again.

    PE Stamps

    Wow, great feedback everyone – thanks. I feel like additional information is warranted, however… In general, the State A stamp would be placed on the ME drawings to “protect” the Civil engineer as a person in responsible charge. The project is a multidiscipline effort. The mechanical...

    PE Stamps

    With the understanding that all States have different requirements for “who is licensed” and “how PE stamps are used”, I have the following question: First, in general terms, I’ll give the background. Lets say we have a mechanical engineer licensed in State A working under the direction of a...
