some question request to answers

07/13/2008 2:47 AM

* If I put a restriction in the gas turbine exhaust what will happen to turbine speed?

* To measure DC current with a Volt-Ohm-Milli-amp meter, how the meter is connected in with a circuit?

*In a three phase system, with ABC rotation, how many degree the phase B voltage lags phase A voltage ?

*which area Magnetic particle inspection will detect defects ?

* what the function of Inductance ?

* How Ammeters and volt meters display on screen?

* Given a turbine generator, which is synchronized to a large utility and producing 50% of rated watts at a 0.9 lagging power factor, what will be increased if increasing the amount of excitation ?

*Where the signal goes to increase load (Watts) ?

* can we open circuit the secondary of an energized Potential (Voltage) Transformer?

* Can we short circuit the secondary of an energized Current Transformer?

* What is the purpose of a Power Transformer?

* what A Differential Protection Scheme for a Generator utilizes which instrument transformer?

* how can interrupt fault current?

* In the event of a Volts per Hertz "fault" in a Generator Protection System what will cause to the Generator Breaker

* what is interlock prevented?

Hello bachar alsaid

Rules for this Forum state that Class or Homework answers should not be asked.

You have asked multiple Questions, each of which looks like a Class or Homework Question.

You have asked these multiple Questions which are in several different fields:

  1. Aeronautical Engineering
  2. Electrical Engineering
  3. Physics

All the answers to your multiple Questions, are available if you know how to use an Internet Search Engine.

For example: Google Results 1 - 10 of about 29,000 for restriction gas turbine exhaust turbine speed. (0.27 seconds)

The obvious [page to look at is:

http://www.usace.army.mil/publications/armytm/tm5-692-2/c-9.pdf

The relevant part of the .PDF document is:

TM 5-692-2

9-4
9-4. Gas turbine system interfaces

d. Engine air system. The engine intake and exhaust systems provide filtered air to the engine and
remove products of combustion from the engine room. These systems may be very simple or relatively
complex, incorporating such features as preheating or pre-cooling of the intake air, or hardened design.
Restrictions or blockage of either the intake or exhaust systems will severely impact engine performance.

I have bold case underlined the answer to your first Question.

So...what I am saying is that if you don't do any work to get the answers, you will never remember the answers.

Thus you will never learn how to get the answers to your questions.

Best to try an Internet Search Engine for the answers to your other Questions, and over the years you should save thousands of otherwise unrecoverable hours of your lifespan, and each time you learn more, you learn it in context, so it is properly retained in the finest computer you can ever use = Your Brain:

Trust that assists you, in learning how to learn.

Kind Regards....
