Answer / Ratnesh Singh

In a Proportional-Integral-Derivative (PID) control system, the integral (I) and derivative (D) components are used to eliminate steady-state errors and improve transient response, respectively. The integral term sums up the error over time to ensure that the controlled variable eventually reaches its setpoint, while the derivative term anticipates future changes in the error by analyzing its rate of change.

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...
