UniT transformer are step up transformer which is connected to generating house & step up voltage from 11/15kV votlage to 220/400kV voltage level as requirement or line design parameter.
It is just like transformer but connected to unit of the generating house that's why we called it unit Transformers.

How do you check a transformer for ac house unit?
Check that the input and output voltages are as required. Check that the transformer is big enough for the current required for the unit you have.
What is the use of isolation transformer in UPS?
It will segregrate the Battery unit and power supply unit,seperate.----Arun
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
What are the limitations of power supply?
Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.
What is the use of ring main unit?
ring main unit is distributing the power supply to meter cubicalAnswerA ring-main unit (rmu) is a piece of switchgear that is used to connect a transformer's primary winding to a high-voltage ring main. It consists of three load-breaking switches, each with three positions: 'on', 'off', and 'earth'. They enable the transformer to be connected/disconnected to the ring; the ring to be 'broken'; or the transformer to be connected to either half of the broken ring. The 'earth' positions allow the transformer's secondary to be earthed, or either half of the (broken) ring to be earthed.
What is the usage of transformer?
The usage of transformer is to produce electricity from a main electric unit
How transformer converts mva to kv?
Transformer does not convert MVA to KV. MVA is unit of power, where as KV is unit of Voltage. Transformer converts voltgae. Step up or Step down.
How do you check a transformer for ac house unit?
Check that the input and output voltages are as required. Check that the transformer is big enough for the current required for the unit you have.

What warning applies to replacing the ignition transformer?
Remove all power from the unit.
How do you know when a transformer is bad on a central air unit?
the air unit never flies below the buildings but the decepticons obviously do.
Can I exchange a 12V 400MA transformer with a 12V 1.25 amp transformer without damaging the unit?
if used for charging-NO if used for supply voltage-yes
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
Who manufactured the Transformer hideaway repo unit in the DFW area?
Not sure of a unit called a Transformer, but Pierce Sales in Henrietta, Texas had one called The Recluse that folded out of a normal pickup truck and turned into a repo truck. There was another unit called The Illusion made by a company in Houston, but I believe they went out of business.
Can you substitute 12V. AC 40va Transformer for 12V. AC 1000ma. Home service-out door fountain?
Yes, the output current of a 40va transformer at 12 volts is 3.33 amps. The replaced unit had an output of 1 amp making it a 12va transformer. By doing this exchange there will be three times the capacity of the new transformer over the old transformer.
No power to home thermostat?
If the thermostat does not have a loose or broken wire coming from your unit than the transformer in the unit may be bad. A transformer is used to step down the power to usely 24 volts or less and is used to run the controls in the unit as well as to power the thermostat. The transformer should be easy to spot. If you are familar with the use of a maltiemeter frist check for the incomimg 110 or 220 volts that should be coming in. Next check the power going out of the transformer. If you have control power at the unit than check it at the thermostat. Some units have a fuse that you can replace. Make sure you turn off the power before doing any work. Hope this is helpful.
