As you can see by the above Thermogram, there are multiple connection problems with these two transformers. But what stands out is the line connection on the LV side.
This is another good example of how Infrared Thermography saves lives! Every day hundresds of pedestrians walk under this connection and these transformers without knowing the dangers that hang above them.
Not only is the connection about to blow, but the actual transformer is clearly overheating and might even blow its top off.
