'Copper loss' (I2R losses) is the generic term to describe energy losses that occur in any conductor (windings, in the case of Transformers and other machines). The term applies, even when the conductors are manufactured from aluminium or other metals. The losses occur due to the temperature difference beween the conductor and the surrounds, causing heat transfer away from the conductor.

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 generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
Why is copper loss negligible during open circuit test?
Copper losses are energy losses from the windings, due to the currents passing through them. During an open-circuit test, there is no secondary current (so no secondary copper losses) and the primary current is very low (so the primary copper losses are minimum).
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
Can you use a dc generator as a dc motor?
Yes you can turn a motor into a generator, if it is a permanent magnet motor.
How do you calculate copper in dc motor?
Copper is not something that is calculated. The amount of copper might be, or copper losses / load losses, might be, but "copper" is not calculated.
How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
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.
Where does copper losses in dc machines?
Copper losses are also referred to as I^2 R losses. Copper loss is due to heating due to the current passing through the copper windings.
How reactive power drives active power?
reactive power depends on motor winding losses and the reason for increasing of temperature. At running condition the motor power reduces by copper loss.
What are copper losses in a transformer?
Copper losses are purely voltage-drop losses (I squared R) caused by the resistance of the windings, as opposed to hysteresis losses and eddy current losses (so-called iron losses), which are magnetic in nature. They are called copper losses whether the winding conductors are made of copper or not, by the way.
Output line drawn in circle diagram of induction motor used to find variable losses and is variable loss change with rotor current?
Yes, the output line used to find the losses, usually for smaller machines we take copper losses equal to the iron losses.
Explain the power flow diagram of induction motor?
The input power, Pin, is reduced by different loss sources in the system. These reductions are the difference between input power & output power. The losses are: PSCL: Stator copper losses, or I2R losses Pcore: Core losses PRCL: Rotor copper losses PF&W: Friction & windage losses Pmisc: miscellaneous losses All of these losses reduce the input power. The output power is the input power minus all of the losses. Pout = Pin - PSCL - Pcore - PRCL - PF&W - Pmisc
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.
How much copper is in a treadmill motor?
how much copper in 250 hp motor
Is motor oil compatible with copper pipe?
Yes, Motor oil will not damage copper.
What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
