To find the number of turns in the secondary coil (Ns) of a step-up transformer, we can use the transformer equation which relates the number of turns in the primary (Np) and secondary (Ns) coils to the voltages across them (Vp and Vs). The relationship is given by: NsNp=VsVp 1....
STEP DOWN TRANSFORM 10 COILS TO 2 COILS 5:1 VOLTS If the number of loops in the secondary coil is more than the primary than the voltage will be more . The is called a step up transformer. STEP UP TRANSFORMER 2 COILS TO 10 COILS 1:5 VOLTS Why transformers are important in transmissio...
step-up generator transformerThe condition assessment of the 190 MVA, OFWF, step-up generator transformer was performed by the mapping of degree of polymerization (DP). The transformer was taken out of service after 36 years and the active part, (transformer core and windings), was removed ...

The same applies to the unit step-up transformer. To protect both the generator and the transformer, volts-per-hertz protection is normally provided. View chapterExplore book Read full chapter URL: https://www.sciencedirect.com/science/article/pii/B0122274105007948...
Using a small step-up transformer, the LTC3108-1 provides a complete power management solution for wireless sens- ing and data acquisition. The 2.2V LDO powers an external microprocessor, while the main output is programmed to one of four fixed voltages to power a wireless transmitter or ...
Equation (8) and (9) are common formulas for calculating the number of neurons15. \(n_{1}\) is the number of hidden layer neurons. n is the number of input layer neurons. m is the number of output layer neurons, and a is a constant between1,10. $$ n_{1} = \sqrt {n + m...
However, the copper transformer oil nanofluid prepared by Xuan et al. [3] can only maintain no precipitation for 1 week at room temperature. Although the one-step method is more stable than the two-step method, the two-step method is more widely used than the one-step method. Because of...
