What are the constant losses in a DC machine?
Constant losses Those losses in a d.c. generator which remain constant at all loads are known as constant losses. The constant losses in a d.c. generator are: (a) iron losses (b) mechanical losses (c) shunt field losses
What are the applications of losses in transmission line?
There are no applications for losses, that's why they are called 'losses'!
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Can a Auto transformer have more load losses than its no load losses?
Power transformers have both no load and full load losses. The key is copper wiring, as copper varies with the square inches of the secondary and primary currents.
What is the effect of frequency change on transmission losses?
Higher the frequency, higher the losses.
What instrument measures losses?
Many different instruments measure losses depending upon the field. For example, reflectometers measure electronics losses and a manometer measures pressure.
What instrument measures electronics losses?
reflectometer
How do you reduce core losses?
There are various measures that can be taken to reduce core losses. Lamination of the transformer core is believed to reduce core losses significantly.
How can you save thermal energy?
There is no way to save thermal energy in the long term; heat tends to escape. You can reduce the losses by some isolation measures, as those used in a thermos bottle.There is no way to save thermal energy in the long term; heat tends to escape.

What is transformer open circuit test?
An open-circuit test measures a transformer's iron losses. With no current flowing in the secondary windings, and only a tiny 'magnetising' current flowing in the primary windings, there is no significant energy lost due to the resistance of the winding conductors. So a wattmeter attached to the primary of the transformer will not read any 'copper losses', only the 'iron losses' that occur in the core.
Can you lose 13 pounds in one day?
No, that is pretty much physically impossible.Answer:Weight losses in this range are possible only with surgery, total blood loss, childbirth, limb loss, compete intestinal evacuation or other drastic measures. Weigh losses are generally felt to be resaonable if they are in the range of 1% of body weight a week.
What are the different kinds of losses in machines?
stray losses,armature copper losses,iron losses(Hysteresis and eddy current losses),mechanical losses(friction and windage losses)

What is the purpose of open circuit test and short circuit test of a transformer?
An open-circuit test is done with the transformer running at its rated voltage but with no load. This measures the power lost in the magnetic core. (IR Losses) A short-circuit test is done with the transformer running at its full rated current in all windings but at a low voltage. The secondary is shorted and the primary voltage is adjusted to give the rated current. This measures the power lost in the copper windings. (Copper losses)
How many graphs are there?
Infinitely many. There is a different shaped graph for each function that can exist. Plus there are graphs for non-functional measures. One of my favourites is Minard's graph depicting the losses sustained by Napoleon's army in Russia. See link.
How many types of losses in transformer?
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
