Does frequency change power?
Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit.
Can I use a 60 Hz device in a 50 Hz power frequency?
Electrical machines designed for 50Hz can usually work safely in 60Hz power supply, but not applicable to 60Hz machines to be run in 50Hz power supply. It is not always easy to just change the machine or equipment to rated frequency considering the FINANCIAL BURDEN that comes with it.
What will happen if transformer is operated at 100 Hz frequency?
Most recent answer. It will draw very high magnetizing current as magnetizing reactance will reduce by order of 10. Hence magnetizing current will increase 9-10 times of rated magnetizing current. This will produce high flux and increase the magnetic flux density (more than rated Bmax), which will increase the losses.
What happens if the supply frequency in a transformer is doubled?
When the frequency of supply to a transformer increases , the following happens: 1) Transformer operates with increased core losses and hence poorer efficiency.
What will happen to the size of a transformer if the frequency is increased?
The amount of magnetic energy that a transformer can ‘store’ is more or less linear in its mass. At a higher frequency, more of these cycles occur, hence the same transformer would transform more power, or the same power can be transferred by a smaller transformer.
What will be the eddy current loss if the supply frequency of transformer becomes double?
What will be the eddy current loss if the supply frequency of a transformer becomes double? Eight times.
When a transformer is operated on a supply frequency higher than its rated frequency what will happen to its KVA rating?
No load Inductive reactance (X0 ) will change with frequency as X=2(pai)fL which will reduced the magnetizing current for the applied voltage V , hence E1. Yet in power ferequency range the overall KVA capecity will be raised with increased in frequency.
