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.
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.

transformer action doesn't depend on power factor that is why we indicate its rating in KVA
Lower the rating of the primary fuse feeding the transformer.
A: The VA rating is there 6v/a the power fuse to blow is 6watts. 050a fuse
For an 800 kVA transformer, the size of the fuse depends on the primary and secondary voltage levels. A common rule of thumb is to use a fuse rating of about 125% of the transformer's full-load current. For an 800 kVA transformer at a standard voltage of 480V, this typically results in a fuse size of around 1,200 to 1,500 Amps, but it's essential to consult the manufacturer's specifications and consider local regulations for precise sizing. Always ensure that the fuse is selected based on both the transformer and application requirements.
100MVA
Depends on the kva rating of the devices to be tested using a transformer.
You need to specify the phase. I assume it is 3 phase system. Then the HT current is 30.3 amps
The recommended power rating for a 16V 30VA transformer is 30 watts.
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.
To open a 12V transformer for fuse replacement, first ensure it is unplugged from the power source to avoid electric shock. Use a screwdriver to remove any screws holding the casing together, and gently pry it open. Locate the blown fuse, carefully remove it, and replace it with a new one of the same rating. Once replaced, reassemble the transformer securely before plugging it back in.
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.
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.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
