Soft Starter main purpose: 1) Provides smooth Acceleration and Deceleration of the motor. 2) Used only in Starting and Stoping of motor and not in normal running condition. 3) No harmonic problem. 4) Varies only Voltage 5) Need to physically change the phase sequence of the motor to cahge DOR of motor. VFD main purpose: 1) Can vary the rpm of the motor along with smooth acceleration and deceleration of motor. 2) Used in both Runing and Stoping condition as well as in Normal running condition. 3) Contains Harmonic problems. (Specially 3rd order Harmonics) 4) Varies both Voltage and Frequency. 5) We just need to cahnge the selection on the VFD pannel to change the DOR of motor.
Sir ek video iss topic pe bhi bna hi dijiye ki motor mai jo 8 RTD lage hote hain vo Khan jese lage hote hain Aapne to overhauling karvaya hi hoga to aapko pta hoga .
Sir, Please make video on control wiring of dol, star delta, rdol dcs operate and local operated... It will be huge benefit for us how are in appreciateship in other company
Sir, how to connect both VFD and soft stater in a motor, pls suggest. Suppose motor running through soft stater and then we want to stop soft stater and run through VFD, kindly explain pls. How to connect motor through both VFD and soft stater.
Commissioning ke baad humko HT n LT feeders ko charge karna hota h to kaun kaun se step follow karne hote h n kaun kaun se test katne hote h iss pe ek video banaa dijiye sir ji🙏🙏
The waveform is not the same because of different power electronics circuit, the value is different you have to calculate active power input and active power output then you can roughly know input current

Just love ur content . Bahut aacha content delivery hai
Very good knowledge sir ,
Thank you very much
Thank you So much sir.....your videos helped me a lot.......
Sir ek video iss topic pe bhi bna hi dijiye ki motor mai jo 8 RTD lage hote hain vo Khan jese lage hote hain
Aapne to overhauling karvaya hi hoga to aapko pta hoga .
Very well explained 👍👍👍
Very well explained.. 👌
Thank you Dinesh..
Sir good knowledge given
👌👍
Sir please make one video on preventive, predictive, breakdown maintenance
Sir please make a detail video about LRS and GRR working
Sir, please make video about equivalent circuit and phasor diagram of 3 phase induction motor.
very nice explanation
Sir please make one video to explain symmetrical and unsymmetrical fault
Single phase or three phase me kya antar hai is pe ek vedio banai ye
Super guru
Sir please tell us about the use of UPS in switchgear room.
Can we use VFD for GRR ( Grid rotor resistance), soft starter we can use for LRS( Liquid rotor resistance)
How frequently use start stop function with soft starte?
Sir, how can u isolate motor and heater in a electric device? Please reply. TIA
Pls describe dyco as in our plant hfrs soft starter with dyco is used
Sir please explain exact operation of NO and NC? it is very confuse for me.
Thanku
Sir ap ek gear box motor par video banaye please
Please make a vedio VFD how to voltage increase
Sir plzz ak video RTCC panel se voltage ko kaise set krte h is pr ak video bna dijia plz request h sir aapse
Excellent thanks
Sir what is the difference between chemical pump impeller and normal pump impeller and made of
Sir, Please make video on control wiring of dol, star delta, rdol dcs operate and local operated...
It will be huge benefit for us how are in appreciateship in other company
Hello sir, please make a video on ESP
Sir What is Troubleshooting?
Hello sir
battery ka charging current kaise calculate kare normal time me
Total 110v ki battery hai per cell 2v 300AH pls reply sir
Sir soft stater kitne hp tak ki motor chla sakte hai
Sir, how to connect both VFD and soft stater in a motor, pls suggest.
Suppose motor running through soft stater and then we want to stop soft stater and run through VFD, kindly explain pls.
How to connect motor through both VFD and soft stater.
You are awesome
Sir g VFD'S may SCLAR AND VECTOR(DTC) starting methods par ak video banao .Specially DTC Method par .
Best 👍🏻👍🏻👍🏻👍🏻👍🏻
Great
DRIVE control wiring diagram of pairametar PDF bejo n Sir
Sir aap coaching karwa sakte hai kya if possible
How to identify main star and delta contactor in star delta starter
Good video
Sir vfd ki control wiring 2wire and 3wire se related video banaaiye please🙏🙏 sir
🎉🎉🎉🎉 very good
Sir please make video on ESP
Please Please please
Sir ek video types of distribution system per bna dijiye like feeder distributer service main radial system ring main or interconnected please sir 🙏🙏
Briefly explain VFD use internal Cards and working princeple
Commissioning ke baad humko HT n LT feeders ko charge karna hota h to kaun kaun se step follow karne hote h n kaun kaun se test katne hote h iss pe ek video banaa dijiye sir ji🙏🙏
Right I also want to know
Thank you sir
Vfd connection & settings k video laiya please
sir VRMS kya hai
Why input current and output current is different in vfd
Because I/p voltage and frequency different.
The waveform is not the same because of different power electronics circuit, the value is different you have to calculate active power input and active power output then you can roughly know input current
Pi test of motor
VFD me ID run kya hota he?
Thank you sir
