Power transformer testing

Power transformers are the central hub in the field of energy distribution and transmission. As such, their condition is critical for reliable, fault-free operation. Any failures can have serious consequences. The resulting overloads of grid sections can lead to far-reaching supply and production failures. A total failure of the insulation can lead to personal injury as well as to immense damage of property.

Preventive replacement after a certain number of operating years is often not an economically viable alternative, since the associated costs of replacing this asset can be enormous and the aging depends on the conditions in which the transformer is operated. Therefore, condition- or time-based asset testing and diagnostics have established themselves as the better option.

Therefore, we have developed a wide range of solutions for testing power transformers that operate in line with international standards (such as IEC 60270, IEC 60076-1, IEC 60076-3, IEC 60076-11, IEEE Std C57.12.00, IEEE Std C57.12.90, IEEE Std C57.113, IEEE Std C57.124 and IEEE C57.127).
