Without knowing what kind of transformer plate your referring to, try these sites: * http://www.purenissan.com/transformer_plate.htm * http://near-fest.com/index.php?topic=314.0 * http://hamradiomarket.com/articles/Amps1.htm short excerpt below: Back when most of us were becoming infatuated with the loud rotating machinery, new kit maker Heathkit designed an amplifier with a light weight low voltage plate transformer and a light weight voltage doubler rectifier/filter circuit. Many in Ham Radio spoke of this arrangement as sissy little stuff and not big and rough and tough enough for Hams. Ha!. The SB220 became one of the finest successes of amplifier design.
Answer: Transformer name plate shows the rating of the transformer...viz., operating frequency, rated current n voltage, output power in KVA, type of insulation used, tranformation turns ratio... Additional Info: in addition to that, you would also find the percent impedance, size of the tank, tap configuration, and vector group. Here is photo of a typical power transformer nameplate: http://www.jcmiras.net/jcm2/p20.htm
I'm not sure I understand the question. If you are asking if it's single or 3 phase, this will be marked on the name plate.
a hole transformer
Transformer has windings
yes we can place auto transformer in place of original transformer
The function of fans in a transformer is to regulate the transformer's temperature.
A transformer that increases voltage is a step-up transformer.
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
The plate should as a minimum show the working voltage, volt-amp capability and the rpm of the generator. Other optional information is the manufacturer and serial number.
A transformer does many things.
