Online tool to Estimate the Ventilation of Transformer Rooms

The SITRATO online tool is available free of charge from Siemens for pressure calculations in case of internal arcing in the transformer room. The tool shows the pressure-time characteristic, calculates the cross-sections for air inlets and outlets, considers the limit values for EMC, and displays the efficiency characteristic.

In addition, the effects of harmonics on the transformer load can be calculated.

As it is saved in a cloud, the data can be retrieved at any point. The results are documented and made available in PDF format.
