You have already completed the quiz before. The unconformityitems mainlyinclude temperature rise, load loss, no-load loss and partial discharge. However , when the transformer is on no-load, excitation. In other words, hysteresis occurs when the change in the system's response occurs with a time delay to the change of the driving force causing it ('hysteresis' comes from Greek hysteros meaning 'later'). 18 Iron (Core) Losses Hysteresis Loss: The direction of the magnetic flux in the core changes every cycle. The coercivity and consequently the hysteresis loop exhibits unex-pected strong frequency dependence. Power is consumed to move around the magnetic dipoles in the core material, and energy is dissipated as heat. Power loss depends on how many times per second the hysteresis loop is traversed. Lowers their power efficiency. . + b) - 1 +In E2 where E1 and E2 are very close to unity and depend only on the ratio a/b (Grover gives. Solution for In transformer, the hysteresis loss depends on load current O only flux density O both frequency and flux density O only frequency Chapter 1. It is well-known that current required is higher when power factor is lower. The loss of hysteresis is shown by a decreased area of the hysteresis loop. It is a kind of loss and is known as hysteresis loss. The effect of magnetic hysteresis shows that the magnetisation process of a ferromagnetic core and therefore the flux density depends on which part of the curve the ferromagnetic core is magnetised on as this depends upon the circuits past history giving the core a form of "memory". The hysteresis loss which is produced in the magnetic circuit under such condition being high, it always reduces the efficiency of the electrical equipment and causes undesirable temperature rise due to heat that results.
