Description of Power Isolation transformer:

SGGF isolation transformer is used to solve the power grid problems which are caused by the photovoltaic power generation,such as harmonic, flickering, DC magnetic bias, and over voltage. Transformers are usually used between power grid and grid-connected inverter which can isolated inverter and sent the power back to grid.

Characteristic of this series:
Standard capacity: 50KVA/100KVA/250KVA/500KVA
Rated voltage:400V/290V
Connection group: YN.yn0
Impedance: 3-5%
Efficiency:＞98%
Overload capacity： 15%
Electric intensity: AC3000V/min, leakage current＜5mA
Under rated power, winding temperature-rise F, less than 100K.
Meterial： High quality silicon steel sheet iron core, which achieves low no-load loss and noise. Enamelled rectangular wire for small capacity, aluminum foil for large capacity, producing with vacuum pressure impregnation which makes transformer high mechanical strength and moistureproof ability.
