<i>Moderator note: This is an unedited or as some would say uncensored post</i> To all: Of late, my posts have attracted a number of Cowardly "Neighsayers" which have far exceeded the number of Thankful "Yeasayers", and I have had enough! My reasons(s) follow: In the 12 years (ca) I’ve...

I said it was difficult to put in words. Also you have confused capacity with impedance. And since I am more old fashioned than you, contact me at: cepsicon[at]aol[dot]com

CSA... Doesn't my belated answer to your specific question merit any comment at all?" Regards, Phil Corso

AIM... the impedance of an infinite (source bus) is always taken as zero, but it doesn't have to be. The bus in your example could be considered "infinite" if the generator connected to it had a relatively large impedance compared to the source bus, say 10-20 times that of the source...

CSA... thanks for the potential "helpful" vote, but no thanks! You have the spot-light, so continue with your answer! However, I would like to give you a word of advice... stop shouting so much!!! Phil

GTG... "Ungrounded Systems" (admittedly low-voltage) can be found throughout various industries, especially the marine industry, including the US Navy. The only argument in favor of "Ungrounded Systems" is the one you cited; a ground-fault will not trip the affected circuit and plant operation...

Madmemed... I forgot to ask you the following questions, earlier: 1) Do you have difficulty when synchronizing one particular alternator with the grid? Or with both? 2) Do you have difficulty when synchronizing either alternator with the other (off-grid)? 3) Are both alternators...

Ali… is your question also related to alternators in a Hydroelectric Plant, like Madmemed? Regards, Phil Corso

CSA... Reviewing this thread after Anthony's 16-Oct-11 (02:28) post, revealed that I failed to reply to your 22-May-09 (13:23) query. I sincerely apologize for not answering! You asked, paraphrasing, "Why is the alternator-neutral grounded if the transformer-neutral is already grounded?"...

EZER... I suggest you contact Allen-Bradley (ABRockwell) for their 2011 document covering Emergency Stop Devices. Following is their conclusion: "There are many global standards that govern emergency stop design and installation. And while there are some discrepancies, the global standards...

JRH... I suggest you start with the white paper: www.Imphotonics.com/pwrfact.htm It is a very good reference that explains the connection (please excuse the pun) between induction motors and power-factor. It also exposes several myths related to the application of power-factor correction...

Ezer... further to my earlier response, there is a rather simple logic-circuit to implement the correct shutdown sequence regardless of the operator's contrary procedure? Contact me if you are interested! Regards, Phil Corso

Ezer... start with: http://control.com/thread/950636217 Regards, Phil Corso

Siddharth… buses having generators connected to them are referred to as generator buses; all others, even without "electrical-loads" are called load-buses. The angle term you ascribed to a load-bus, i.e., "power-angle" is non-existent! Instead a bus has a voltage magnitude and a corresponding...

Abdul... As a start I suggest you refer to the examples given in USA's NEC (National Electric Code) Handbook; also known as NFPA 70. Regards, Phil Corso

Satish... start with http://control.com/thread/1245083704 Regards, Phil Corso

Zarir... see pg 5.2.4 of the Manual! Regards, Phil Corso.

Sensorless... can you send photo of the Xfmr's nameplate? Phil Corso ([email protected])transformer.

Again, for those still interested... the July issue of I.E.E.E Spectrum Magazine, has an article covering "Flywheels Keep The Grid in Tune!" There is also mention of a study, carried out several years ago by USA’s D.O.E., proving that frequency-dips could be corrected by temporarily...

Rakabob... I suggest you start with Control.Com thread: http:///control.com/thread/1293373042 Regards, Phil Corso
