Teri Variac produced by wrapping the wound enamelled copper wires on top of the toroidal core sheet; usually
a variable AC voltage source AC is used to obtain the constant voltage source. Active
a carbon brush 0 - 330 forms of variable levels of turning on the coil. Control
manual or servo motor can be achieved.
BENEFITS
1. Type power decreases magnetic core section becomes smaller, and therefore less steel used iron
Reduced losses.
2- less copper is used for the single winding used and reduced copper losses.
Regulation 3 percent compared to the second coil transformers for the fugitive mind is less is better.
4- * Can be removed very flew out various voltages can be readily obtained.
5- less material is used for lighter, more economical and more efficient.
