Question:

What is the transversal and semi-crossing problem of the transformer?

What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.

Answer:

(4) Splitting coefficient: The ratio of split impedance to crossing impedance. The description of the method of the standard method shows that the commutation reactance measurement of the rectifier transformer is similar to that of the transformer short-circuit impedance measurement. The difference is that the measurement of the short-circuit impedance is usually made by connecting the low-voltage side of the transformer and the high-voltage side to the rated current, And the commutation reactance measurement of the rectifier transformer is to short-circuit the high-voltage side and to measure the voltage between the terminals at the low-voltage side with the rated single-phase current. It can be seen that the commutation reactance of the split transformer is a half-crossing impedance.
(3) split impedance: two short-circuit between the low-voltage winding impedance, that is, high-voltage winding open circuit, a low-voltage winding short circuit, another low-voltage winding power supply when the equivalent impedance. Where the reactance component is called split reactance.
Dual split transformer compared with the general power transformer, there are four important impedance parameters: (1) through the impedance: two low-voltage winding in parallel, the high and low voltage winding short-circuit impedance, that is, high-voltage winding short circuit, two low-voltage winding in parallel after adding the current equivalent impedance. Where the reactance component is referred to as crossing the reactance. (2) half-crossing impedance: one of the two low-voltage windings open, the other low-voltage winding between the high-voltage winding short-circuit impedance, that is, high-voltage winding short circuit, a low-voltage winding open, and the other does not open the low-voltage winding power Value impedance. Where the reactance component is called a half-pass reactance.
