OKERDA designs and produces high quality Torodial Transformers for pure sine wave inverter with high
efficiency, low inrush current and low noise characteristics which are popular in the market. We also make
Reactor Inductor for Inverter of Solar Power with low loss and low noise.




Testing process 
1. No-load test (included no-load voltage, no load current and no load loss);
2. Inductive voltage test;
3. Load test (load voltage and temperature rise;
4. Temperature rise test;
5. Insulated resistance;
6. Hi-pot test;
7. Leakage inductance test;
8. DC resistance test;
9. Surface inspection.
