A current transformer step downs the current in a power circuit to a lower amperage.
A voltage transformer steps down the voltage in a power circuit, typically to 110 volts AC for residential and business use.

∙ 12y agoIn case of current transformer the voltage is constant. we can step up or step down the current rating. In case of Voltage Transformer the Current is constant. We can step up or step down the voltage ratings.

∙ 10y agoThere is no read difference between the two, although a neutral CT is wired in the reverse polarity to cancel out currents crated by the secondary phase CTs. Check out this article for more information on CTs: http://www.testguy.net/current-transformer-ct-basics

What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What is the difference between a battery charger and a transformer rectifier?
A battery charger is a DC voltage source followed by some kind of regulator that controls the current flowing into the battery. Depending on the type of battery, this regulator might be simple, based on current and/or voltage, or it might be complex, based on voltage slope. A transformer rectifier is simply one of the part of the DC voltage source.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
What is the difference between isolation transformer and Automatic Voltage Regulator?

4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
Can a constant dc current can induce a steady state voltage in a transformer?
No, the current has to change for a voltage to be induced in the transformer.
The difference between a transfer and a rectifier?
A transformer is basically used to step up or step down the main power supply. The rectifier is used to convert an alternating current (AC) or voltage to direct current (DC) or voltage.
Why transformer rating is not given in kw?
Transformer rating is based on the maximum temperature a transformer can run at. This temperature is dictated by the amount of current flowing through the transformer windings. This is why transformers are rated in KVA (voltage * current), not kW - it doesn't matter what the phase relationship is between voltage and current, just the magnitude of the current.
