State of corona discharge between core and winding of single phase induction motor
It is a state of corona discharge between core and winding of inner diameter about 60 mm of single phase induction motor. The CORONA-i XT series is tested with a signal of several tens of kHz, it can detect discharge through an insulator (dielectric) that can not be detected with direct current or AC 50/60 Hz.
State of corona discharge in coil
It is the appearance of the corona discharge in the coil made to observe the corona.
It is very difficult to look at the corona from the outside because the actual transformers and coils often discharge internally.
The CORONA – i XT series detects and displays this discharge.
