what is the relation between frequency and inductive
reactance in a d.c supply?
Answer Posted / iamdon
As far as DC is concerned, there is no concept of
frequency and reactance.
The concept of frequency and reactance(Inductive or
Capacitive) is valid only for A.C.
In AC,
Inductive reactance(XL)=2*pie*f*L
Capacitive reactanc(XC)=1/(2*pie*f*C)
Where f=frequency,L=Iudctance.C=Capacitance

What is core CT & it's function?
generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
