diz is a controversial question,anyway i write my opinion
since E is directly proportional to f (E=4.44fBAT).....therefore the KVA changes on change of frequency..........
this is common thought,but what the controversial thing is why the current can't compensate the KVA rating to maintain it constant........
IN GATE book of G.K publishers the answer is IT DOES NOT AFFECT.
What else can I help you with?
What formula would be used to convert at current transformer rating at 60Hz to 25Hz?
I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
Can you operate a transformer below kva rating?
What limits the use of a transformer is its operating temperature, as excessively-high temperature will act to break down its insulation. The temperature reached by a transformer is a function of its rating (expressed in volt amperes), so operating a transformer below its rating is perfectly okay.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
Transformer rating is expressed in?
VA or KVA or MVA
Why are short time rating of transformer is high?
Because a transformer is a big lump of metal that takes time heat up, so if the load is on and off in a short time, the load rating can be exceeded.
What formula would be used to convert at current transformer rating at 60Hz to 25Hz?
I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.
Can you lower 277v to 240v?
Yes, you can lower the voltage from 277V to 240V using a transformer. A transformer can step down the voltage while maintaining the same frequency. Make sure to select the appropriate transformer with the correct voltage rating for the input and output you need.
Why the rating of a transformer is given in kVA?
The rating of a transformer follows the two magnitudes that affect its operation; Volts and Amperes. The other, more popular parameter (kW) is not used on transformers because it depends on connected load Power Factor.
What is the maximum transformer rating for distribution transformer?
100MVA
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
What is the recommended power rating for a 16v 30va transformer?
The recommended power rating for a 16V 30VA transformer is 30 watts.
What type of step down transformer would I need to make a 'Numark Mixdeck' work in the UK if I were to buy it from a US store online would a 500 watt transformer be enough to power this in the UK?
Transformers are rated in V.A (volt amperes), rather than in watts. You will need to determine the rated power (in watts) of the Mixdeck, and then ensure your transformer's rating exceeds this value. You will also need to determine whether the change from 60 Hz (US) frequency to 50 Hz (UK) will affect the operation of the machine.
What does the power rating of a transformer imply?
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.
Can you operate a transformer below kva rating?
What limits the use of a transformer is its operating temperature, as excessively-high temperature will act to break down its insulation. The temperature reached by a transformer is a function of its rating (expressed in volt amperes), so operating a transformer below its rating is perfectly okay.
Do the load carried by a transformer is affected by KVA rating?
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
