1200 kVA Substation Transformer

1200 kVA Transformer Specifications

The SL-1200 kVA-13.8 kV-0.24kV transformer is a three-phase unit with a power rating of 1200 kVA. It operates using the ONAN (Oil Natural Air Natural) cooling method, providing efficient cooling without the need for additional cooling equipment. The transformer has 5 tap positions for voltage adjustment.

The vector group of the transformer is Dyn11, which denotes the winding connections. The high-voltage (HV) side operates at 13800V, while the low-voltage (LV) side outputs at 240V.

The transformer exhibits a load loss of 14000W when operating at its rated voltage and a no-load loss of 1800W. With an efficiency of 99.18%, it demonstrates optimal power conversion efficiency.

The impedance of the transformer is 4.50%, indicating its ability to handle variations in load and provide stable voltage output. It is color-coded in ANSI 61- Gray.

Additionally, the transformer has a K-factor of K-13, representing its ability to handle harmonics and non-linear loads. This ensures reliable operation even in environments with high harmonic distortion.
