Answer / balamurugan

wide range of speed control is available because we can
vary the firing angle from 0 to 180 degree

Answer / naveen

Most economical operation when cost cosideration, accurate
operation will possible

Answer / arockia doss

Advantages :

1. Fast Switching Characterestics than Mosfet, BJT, IGBT

2. Low cost

3. Higher Accuract.

Answer / tarequl islam mukul

It can set a trigger voltage,then the output current and voltage varies and the desired dc current can be achieved for motor.

Answer / gagan gumar gupta

we can easyly change firing angle of thyristor from 0-180
it is also economical.its speed control is so fast than any
other thing.

Answer / rehan

the main advantage is that ........ we can switch on and
off the device nd vary the waveform in accordace 2 the
firing angle with the same ckt

WE HAVE A LOAD OF 55KW MOTOR ITS VOLTS 380 3PH AND ITS TAKING 100AMPS (ITS FULL LOAD IS 105AMPS)AND ITS CABLE IS 4CX50SQMM ,NOW ITS GETTING ABNORMAL HEATUP IN CABLE,PLZ TELL WHY ITS HEAT-UP?(CABLE LENGTH IS 15 METERS ONLY)

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...
