Transformer Diagnostics

Transformer Diagnostics

Regularly scheduled standardized electrical tests are an effective way to gain a reliable insight into the operating condition of your transformers.


Power transformers are a critical component in energy distribution and transmission. Maintaining them is vital for reliable, fault-free operation. Any failures can have serious consequences. The resulting overloads of grid sectors can lead to far-reaching supply failures, as well as personal injury and property damage.


Preventive replacement after a certain number of operating years is costly, and unnecessary where good maintenance systems are employed. These systems include condition- or time-based asset monitoring. Diagnostic testing is a cost-effective tool, especially if problems are suspected or the transformers are positioned at strategically important locations (such as in a power plant).


In conjunction with utility clients from across the country, Meridian Labs has developed a wide range of testing for power transformers that are in line with ASTM and IEEE practices.
