    Step and Touch Potentials

    Hi I have studied IEEE std for this stuff but never happend 2 get chance 2 work but a curosity after jghrist reponse: As you said: If no neutral, GPR would not go beyond Ph-g voltage, the normal acceptable value of GPR according to Canadian Electrical Code is 5000 v that means if we consider...

    Generator Rating

    I mean if we have FLA and LRC, can we find all the values given above or manufacturer has to provide us with that. Thanks

    Generator Rating

    I found this discussion interesting, so thought should participate, so the parameters mentioned below Rotor Resistance (Rr): p.u. Rotor Reactance (Xr): p.u. Stator Resistance (Rr): p.u. Stator Reactance (Xr): p.u. Magnetizing Reactance (Xm): p.u. Short Circuit Reactance (Xd”): p.u. will be...

    Generator L-G Fault

    It depends upon, what type of grounding it has, As SLG fault is supposed to be less that 3 ph fault so I=E/(X1+X2+X0+3XN) this is calculation for fault

    Fault Current Calculation

    Hi, From what I have understood, you have a RMS fault current, take its reciprocal multiply by the base MVA and you got it. cheers !

    STANDARD FOR GENERATOR FACTORY TESTING

    There are IEEE standards for generator testing, go to IEEE website, and look in to it, If you could not find an IEEE standard let me know, I will get the info. cheers !

    Circuit Calculations

    Hey Gassy This is a 3phase system, all the currents are in a 120 degree relationship, you just cannot add them algebrically, now when the load is unbalanced, the term" how much current is not relevant but as varri79 said max. current is 7.2 A that will work" the other thing you can do it to find...

    Line impedance calculations

    For what application, you are looking for this calculation, normally you can get this thing from the manufaturer and the angle you are talking about is the angle between the Sending end and receiving end voltage. if this is what you are looking for, you have to calculated it using basic...
