Zig-Zag Transformers
Double Output
Applications:
b Three phase four wire electrical
system with single phase nonlinear load such as lighting ballasts,
computers, printers etc.
Technical Data
3
The (0° / -30°), series double output
transformers are specifically designed
to reduce third harmonic (and 9th, 15th,
21st...) voltage distortion at the load and
to cancel third (and 9th, 15th, 21st...),
5th, 7th, 17th, 19th... harmonic currents
in supply.
These transformers are high-quality three
phase transformers equipped with an
electrostatic shield.
Unlike K-rated transformers, which are
designed to survive in installations having harmonics, this series transformers
reduce harmonic currents in supply.
