|
|
X2 is located directly under H1 on a transformer, how are these terminals mounted ? |

|
What test is performed on a transformer to determine its percent impedance? |
Short circuit test |
|
|
What transformer would you use where output voltage is to be higher than input voltage? |
Step up |
|
|
Why should you not apply more than 110% of the rated voltage to the primary winding of a transformer? |
Primary current will increase to an unacceptable level and will BURN OUT the transformer |
|
|
What is “FCBN” and when is it used? |
Full capacity below normal. Used when primary supply voltage is lower than rated transformer primary voltage |
|
|
What is “FCAN” and when is it used? |
Full capacity above normal. Used when the primary supply voltage is higher than the rated transformer primary voltage |
|
|
What is “RCBN” and when is it used ? |
Reduced capacity below normal. Used when the primary supply voltage is lower than the rated transformer primary voltage |
