How do you minimize core losses?

Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb


How eddy current losses andhysterious losses can be reduced?

eddy current can be reduced by using laminated cores. and also be reducing the thickness of the stampings. transformer iron loss is the combination of eddy current loss and hysterisis loss. both the losses depend on core of the transformer and iron loss is a constant loss.


Why should we separate the core losses?

separation of core losses are necessary to determine core losses at diffrent frequency.........


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 do you reduce core losses in distribution transformer?

Reducing core losses is a design responsibility of the manufacturer. They do this by laminating the core (to reduce eddy-current losses) and carefully selecting the type of material used for the core (to reduce hysteresis losses). There's very little that you, as the user, can do about reducing core losses.


How is the core losses occur?

The core loses occur because of the stator and rortor.


Why core losses are always fixed in transformer?

Core losses are losses in the magnetic system of the transformer, such as eddy currents in the core, hysteresis losses, etc. Because of this, the losses are constant, regardless of load, assuming voltage and frequency stay fixed.


Why core losses are negligible in short circuit test of transformer?

I am so sorry for your core losses


Core loss of an induction motor?

Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.


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.


Is no heat loss and no core loss the same thing?

No. Core losses would be hysterisis loss and eddy current losses. Heat losses most likely is referring to I2R (I squared R) losses, which is losses due to the resistance of windings, and is dependent upon loading. There are other losses that are not heat related and core related - such as losses due to vibrations (the core is a major player here, but part of the noise is from windings and cooling systems). I've never heard someone refer to losses as "no heat" or "no core". These are fundamentally impossible - there WILL be core losses, and there WILL be I2R losses if you have a transformer and it is loaded.


What are the losses of a transformer?

Various energy losses occur in transformers:Copper losses, the resistance to the current flow in the windings which heats the conductors.Iron losses, which are of two kinds:eddy current losses which flow in the laminations of the core caused by the magnetization and re-magnetisation of the core, which also causes heatingof the core. Eddy current losses can be greatly reduced by not making the out of a solid piece of iron. That is why transformer cores are generally made of lots of separate thin "laminations" which are insulated from one another by being bonded together using an epoxy resin adhesive.hysteresis losses which are again caused by the magnetizing and de-magnetising of the core. These are reduced by making the laminations of silicon steels, which have lower hysteresis losses than plain iron.Together all these losses lead to a total efficiency of about 97 to 98%, which will alter depending upon the load current that the transformer is supplying.
