A pulse transformer is a transformer that is designed for
transmitting RECTANGULAR ELECTRICAL PULSES(pulses with fast
rise and fall times) of a relatively CONSTANT AMPLITUDE. A
Pulse transformers by definition have a duty cycle of less
than 0.5.

Small power versions are used in digital logic and
telecommunications circuits.
Medium-sized power versions are used in power-control
circuits such as camera flash controllers.
Larger power versions are used in the electrical power
distribution system.

To minimise distortion of the pulse shape,a pulse
transformer needs to have
1)Low values of leakage inductance and distributed
capacitance.
2)High insulation resistance and high breakdown voltage.
3)Good transient response.

I have two AC generators, the first rated 2680KVA for 380V/4345A/pf:0.7 and the second rated 3461KVA for 5500V/363A/pf:0.8. I want to parallel the two generator to a bus. The second generator passes through a transformer to down the voltage to 380V and a part of its power goes to another bus so that it's only a part of the total power of the second generator taht goes to the considered bus. I have two Basler DECS100 AVR regulator. How can I make the synchronization ? What others equipments must have ?
