Three phase excitation Transformer 10kva/10kv or above with IEC/ISO9001 certificate

The excitation transformer is a kind of device which provides three-phase AC excitation power supply for generator excitation system. The excitation system transforms three-phase power supply into generator rotor DC power through SCR, forms generator excitation magnetic field, regulates SCR trigger angle through excitation system and achieves the aim of adjusting voltage and VAR of motor. It is usually connected to the outlet of the generator since the output voltage of the generator is higher, but the rated voltage of excitation system is lower, so a step-down transformer is needed.

The core of excitation transformer applies high quality silicon steel sheet. The coil applies high temperature-resistant wire which effective reduces loss and improves efficiency. The insulation part adopts high temperature insulating materials, which could improve the resistance of high pressure, insulation grade and service life. Excitation transformers have advantages of beautiful design, large power density, small size and high space utilization
