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 is the meaning of fettling?
The removal of the seam left by the mould in greenware, by fettling knife and/or sponge.
How did the fettling knife get its name?
A fettling knife is used to finish pottery by removing defects present in ceramics after casting. It comes from the Middle English word 'fetle' which meant to shape or prepare.
What is a fettling knife?
It's a tool used in ceramics that helps an individual shape clay.
What has the author K Sivayoganathan written?
K. Sivayoganathan has written: 'Fettling and hand arm vibration'
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)

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.
What is another name for evaporation losses?
Another name for evaporation losses is vaporization losses.
How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
Is it correct to say losses?
Yes, losses is the plural form of loss, e.g.:The company's losses were huge.Manchester United suffered several losses at the start of the season.
What are core losses?
Iron losses are termed as core losses. There are mainly two losses - Copper loss and iron loss. Iron loss is no load loss.
