励磁变压器特点

Feature of excitation transformer A three phase excitation transformer, dry type with epoxy resin,

isolation class 155(F).

Electric shield between primary and secondary winding of transformer

The transformer equipped with a temperature detector device and the measurement and alarm signals can be transmitted to DCS.

Pay great attention to the electric loss increased due to harmonic component in the current wave.

Excitation transformer capacity meets with the requirement of field forcing and all kinds of generator operation condition.

CTs for measurement and protection could be arranged on low voltage and high voltage terminals.

The final data of transformer can be mutually agreed with customer based on specific requirements.
