What is the maximum transformer rating for distribution transformer?
100MVA
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.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
How the ka rating of mccb is calculated?
ka of mccb=transformer(KVA)x100/1.732xsecondary voltagex%impedence of transformer
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
What can you do as preventative maintenance for a power pole transformer so that the mineral oil does not boil?
Lower the rating of the primary fuse feeding the transformer.
A transformer is rated at 12V-0-12V and 250mA so what does the 250mA mean and how do you calculate the fuse for the primary winding without knowing the VA rating?
A: The VA rating is there 6v/a the power fuse to blow is 6watts. 050a fuse
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 fuse rating in HT side of 11.4kv500kva transformer?
You need to specify the phase. I assume it is 3 phase system. Then the HT current is 30.3 amps
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.
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.
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.
How do you figure out the amps of a transformer when it only tells you it puts out 20 vdc?
I suspect you are referring to an external power supply for a device, which consists of a transformer and a smoothing circuit of some kind. Look on the device it powers, there may well be a rating plate or an input fuse. You might also find a VA rating or wattage rating. If so, Google for power formulae to manipulate to find amps.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
