Specification of TRAFINDO 20 KV Distribution Transformer
Distribution transformer or B2 transformer / medium voltage transformer is a transformer that distributes
voltage systems in Indonesia with a standard input of 20 KV but we can make
with special specs 3 KV, 6 KV, 11 KV, etc., output 400 Volt, 1/3 Ph, Freq 50/60
Hz, with copper/ CU or aluminium / AL material, with PLN standard area code. With D3 / SPLN 2007 standard and
SPLN 97.50, IEC. Onan or dry transformer. The voltage transfer system (Tap Changer) at 2.5% -5% -10% is carried out by TapChanger operation which is moved outside the tank with the transformer in an off load condition.
We provide routine tests:
Test Ratio
Insulation Test
Iron Losses Test
Copper Losses Test
Impedance Test
Resistance Winding
Dielectric Test
Overvoltage Test
