Team
A little info from expt today to investigate MOT saturation;
Method
1) place large Cap across Secondary to keep low Z across winding (10000uF)
2) measure primary winding L with L meter in above configuration
3) place 12v battery across secondary system to put 150mA into sec winding
Result L meas dropped from 65mH to 47mH with secondary current at 150mA
To confirm technique SC acrooss Sec winding with Cap in place did not affect
measurment. No load Lmeas on primary is much greater and was 300mH
Conclusion
L of sec drops very rapidly and even at a modest 150mA L has dropped by
18mH, implications for use as DC charging reactors
