Is it safe to use a step down transformer rated 16 Volts and 40 VAC in place of required transformer rated 24 Volts and 40 VAC?

Transformers that operate specific devices should be matched to the specific voltage on the device that the manufacturer specifies.

What will happen if a modified sine wave inverter with 115 Volts output is used as a power source wherein a step up transformer is plugged into it to get a power output of 220 Volts?
It will work, but the transformer will not be able to supply its full rated load, because of the harmonic distortion of the non-sine wave output of the inverter. The transformer will also probably run a little hotter too. If you are talking a small load fed from a transformer much larger than required, probably nothing to worry about. But if the power level is large, or you are loading the transformer to more than 30 or 40% of its rated VA, you could run in to trouble. Monitor voltages and temperatures carefully (and have a fire extenguisher handy...)
How can measure transformer KVA?
the capacity of a transformer is defined as a product of voltage and current flowing through it.AS THE CURRENT IS MEASURED IN AMPERES AND VOLTAGE IN VOLTS, Hence transformers are measured/rated in KVA
What is the capacity 0f 100 KVA electric transformer?
KVA means thousands (K) of volts (V) times Amperes (A). A 100 KVA transformer can deliver 1000 amps at 100 volts or 500 amps at 200 volts etc.
How many turns does a transformer need to take 137V on the primary and produce 47V on the secondary with output current of 20A for a 5kVA stabilizer?
You will need a 3:1 ratio transformer. An output current of 20 amps and a secondary voltage of 47 volts, results in a transformer rated at 940 VA.
What is the measurements of 75 kva transformer 3 phase?
For a single-phase transformer, divide the ratedapparent power (expressed in volt amperes) by the voltage rating (expressed in volts) of the primary winding; this will give you the rated primary current (expressed in amperes) of the primary winding.
How can you measure the power rating of a 1.5 kg step down transformer that converts 240 volts to 112 volts?
You cannot 'measure' the rated power (or, more accurately, 'apparent power') rating of a transformer. You can, though, calculate this value, which is the product of the rated secondary voltage and the rated secondary current, and is expressed in volt amperes.This information can be found on the transformer's nameplate data label.
Will a switching power supply work on 277 volts?
Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.
480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
What is rated voltage in transformer?
A: A transformer will transform the AC input to a low or hi output as required by a ratio of input to output. The power will be expressed a KVA or kilo volts to ampere ratio. It also will have a rating of maximum voltage for the simple reason of winding to winding insulation and primary to secondary isolation because if breakdown occurs the transformer will burn out promptly.
How do you calculate current capacity of transformer?
The secondary winding's current rating is the rated apparent power of the transformer (expressed in volt amperes) divided by its voltage rating (expressed in volts). This applies to both step down, and step up, transformers.
If a centre tap transformer rated as 12V-0-12V 1Athen what will be the secondary current of that perticular transformer?
The output voltage of a transformer is not connected to the maximum rated current. You state that the transformer is rated at 12-0-12 at a current of 1A, therefore the maximum (rated) current on the secondary would be 1A. Normally, transformers are rated in VA (volt amps) which is simply voltage x current, the voltage across the two 12v terminals would be 12+12 volts, making the rating of the transformer 24VA.

Does a transformer convert the current from 240 volts to 120 volt?
Transformers are rated in KVA or VA (volt-amps). They transform voltages from one value to another. The current in a transformer is inverse to the voltage. This is why transformers are rated in KVA and smaller ones in VA.
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
What will happen you f the rated power of transformer is changed?
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.
What is the capacity 0f 100 KVA electric transformer?
KVA means thousands (K) of volts (V) times Amperes (A). A 100 KVA transformer can deliver 1000 amps at 100 volts or 500 amps at 200 volts etc.
