The temperature rise is not considered in OC & SC tests of transformers.. But in Sumpner's test, temp. rise is considered.. Hence is called "Heat-run test".. Also, the transformers draw only the power req. to supply core & Cu. losses of transformer..
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
Henry Orenstein invented transformers.
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
There's not a lot to go wrong in a transformer. You can test with an ohm meter (resistance meter) to check that the wires aren't broken if you know what the connections are. It will read low around 10 ohms if the wires are OK and will read very high if they aren't. However there is a slight possibility that if it is damaged some of the wires may have shorted out so it will still read OK but will overheat when you put full power on it. So you need to power it up and check the output is what it should be with a voltmeter set on AC for a suitable scale. Be careful not to electrocute yourself.
Hi-pot and megger tests are common to check the insulation on transformers, motors, refrigeration compressors, etc. They help check the condition of equipment to avoid a future falure. High votage test are conducted in current transformers by shorting the seconday and earth,can apply 3 times the rated voltage
There are Several types of transformers are there in that some are listed below. Instrument Transformers Step Up and Step Down Transformers Single Phase Transformers Power Transformers Distribution Transformers etc. For more visit transcon industries.

They have not released a list of the Transformers yet.
Transformers (2007) , Transformers: Revenge of the Fallen (2009) and Transformers: Dark of the Moon (2011) .
There's Transformers, Transformers: Revenge of The Fallen, and Transformers: Dark of The moon.

Pre-commissioning and commissioning are words used in the engineering field. Pre-commissioning begins many months before the start of the project. During this phase duties are assigned.
the first Transformers movie is simply called Transformers
