What is the design value of short circuit ration of generator?

short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.


What is short circuit ratio?

Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.


What current would you expect an alternator to develop in the event of a short circuit?

maximun through the alternator.


Define generator short circuit ratio?

Checked Stephen J. Chapman's Electric Machinery Fundamentals page 287. It says: Short Circuit Ratio (SCR) for the synchronous generator is the ratio of the field current required for the rated voltage at OPEN circuit to the field current require for the rated armature current at SHORT circuit.


Can an alternator short out for years And have problems for periods at a time for a matter of 3 years or so?

An alternator cannot "short" out for years or even minutes. The definition of a short is a wire or circuit touching ground to cause a fuse to blow. The circuit is too "short" for the current to flow through the proper load and back to the battery. The voltage regulator in a alternator can act up from time to time and cause improper charging from the alternator. Or a component of the alternator can go bad and cause a charging system problem intermittently. Your question needs to be explained better to give a better answer.


How do you calculate short circuit capacity of generator by using reactance of the winding?

The short circuit capacity of a generator can be calculated by dividing the generator's reactance by the sum of the generator's reactance and the total reactance of the system. This ratio will give you the short circuit capacity of the generator in relation to the total system capacity.


Is there any effect on fault level if generator short circuit ratio is high or low?

Probably... What ratio? X/R? X0/X1? X0/R0? Xd /Xd''? etc.


What fuse controls the alternator in 2004 ford f-150?

Alternators are not in a fused circuit. If your alternator isn't working, it's because either the belt is broken, there is a shorted circuit somewhere, or the alternator is faulty.


When you will get to know that short circuit will happen?

1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?


Why alternator is much less likely to burn out on a sustained short circuit than a separately excited dc shunt generator?

Because the Power Factor is over corrected.


98 s10 pickup only runs on battery not alternator how do you fix this?

Simple, have the alternator checked and if it is okay, check the alternator circuit to the battery


Will a bad ground wire ruin an alternator?

a bad ground wire can ruin an alternator by not completing the circuit
