Sir aap CSD(control switching device) ke bare me detail lecture banao jo ki circuit breaker me use hota hai aur ye work kaise karta hai
Sir aap line reactor and bus reactor ke bare me detail lecture banao please
Sir after steady state NTC temperature will decrease or not? If temperature reduce then again resistance will increase.

Same question reply sir
Mistake in explanation started at counter No.4;46 ---> 4;52. High no load current will not flow because NTC being cold - at high resistance, cannot pass inrush current, So your explanation becomes inverted. Pl, you can recheck by correct reasoning & by using a suitable Wattage series lamp, or a CRO to confirm practically. I Like your videos, you gave good step by step explanation, So i want you to be faultless.

Thank u... For ur keen observation. Yes, in stage 2 the NTC offer high resistance and thus cause low inrush no load current. That is why we are using thermistors. But, here i want to say that, during transient stage, there exist high inrush current and to tackle it the thermistor offer high resistance. At 14:20, i comapare the transient current with and without thermistor. Here i signify that the transient current with thermistor is lower than without it. I hope this explanation will satisfy u. I
