Senthil... have you searched Control.Com Archives? Regards, Phil Corso

Josey... see: http://www.control.com/thread/1026150987 Regards, Phil Corso

Engineer… I directed you to the wrong reference, so here is the example solution: Using my Gi.Fi.E.S. method (pronounced Jiffys) for the problem solution, where Gi is for "Given"; Fi for "Find"; E for "Equation(s)"; and S for "Solution", then the answers to your two questions are:<pre> Q1/A1...

Engineer... if the transformer is fed from an infinite source, that is, there is no impedance between the source and the Xfmr's primary terminals, then input voltage will remain constant. Input current = kVA/[Sqrt(3)x(primary kV] If there is a primary impedance, then see the example...

Das... following are several Control.Com threads that discuss the consequencs of HV and LV open-phase operation of xfmrs! http://www.control.com/thread/1026239176 http://www.control.com/thread/1284199900 http://www.control.com/thread/1304477144...

Pitchblend... your choice is an excellent one, BUT, two caveats: 1) Ground all foils and sheath at one end... preferably the source-end if the source, too, is grounded! 2) The 1-Amp current carried by power-pair presents no problem! However, if either conductor is intentionally earthed...

Divyalakshme... this is a classic controls problem often given in Controls Courses and Tutorials. The answer will be found on the WEB! Regards, Phil Corso

Baggy... can you provide additional detail regarding the generator and the motor! Regards, Phil Corso

Bikey... see: http://www.control.com/thread/1026212105 Offer still holds! Phil ([email protected])

Cyanogen ... can you provide additional installation details to determne if an inferential-method is possible? Regards, Phil Corso

Biky ... by heat-load do you mean Heat produced in an electricl control panel? Regards, Phil Corso

Pitchblende... 1) what is connstruction of the RS-485 cable. 2) What is conctruction of the 24V cable? 3) What is current-magnitude (ma or A) in the 24V cable? Regards, Phil Corso

FF... there are Soot-Blower strategies! I suggest you contact Walt Boyes, a frequent controls contributor to this forum! Regards, Phil Corso

Shaheed... Has the problem been solved? Regards, Phil Corso

Dibin ... can you explain why you believe the circuit-length multiplier '3' should be used instead of '2'? Regards, Phil Corso

Panthripu... I strongly disagree with your conclusion. Quite a few threads can be found in the Control.Com archives. I suggest you start with the latest: http://www.control.com/thread/1310129369 Regards, Phil Corso

Shaheed ... thank you for your prompt response to my request for the Test Report! I have to agree with your "feeling" about the test! I believe you are entitled to ask the following questions: 1) The Stator primary and secondary winding DC-Resistance-Test values have been listed but where...

Shaheed... further to my earlier post coverng Taps: Tap '1' approx +5.0% Tap '2' approx +2.5% Tap '3' Nomimal Tap '4' approx -2.5% Tap '5' approx -5.0% Phil

Shaheed... the test vaues, i.e., 1,082.4 Volts applied to the primary terminals that caused 1,050 Amps to flow in the shorted secondary yield a %Z of 9.84% (1082.4/11,000) I don’t know how the Test Company determined it was 9.542%! Perhaps, correction factors were used because of significant...

Chris... presuming you are also interested in low cost, then I agree with Martiny’s lamp suggestion! However, I don’t agree with his "Dark-Lamp-Method' of synchronizing! Instead I suggest a safer approach. Called the "Rotating-Lamp-Method", it uses three lamps; two-bright and one-dark...
