The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…

The project was sponsored by Government of Gujarat for 10 MW Canal-top Solar Plant at Vadodara. The students are thankful to their guide Asst. Prof. Avipsa Dey for her support and encouragement during the project... - Avipsa Dey, Nishi Shah, Sonali Ghatge, Vaishali Sapkal
With over 30 years of experience in motor control, Fairford Electronics is uniquely positioned to provide honest, unbiased and reliable information.
Different fluids have varying characteristics and are usually pumped under different conditions. It is therefore very important to know all relevant product and performance data before selecting a pump... - Dr S S Verma
In today’s world, you could be forgiven for thinking that electrical machines, motors and generators are being reinvented. Energy efficiency, electromobility or having to adapt...
This article presents a simplified analysis of ZSI and the steady state operation of 3-Φ induction motor fed by ZSI. Results of simulation study and experimentation are also included... - Prof. Adarsh J Mehta, Dr. Ashwini A Godbole
Rheostatic starters utilise one or several resistors for obtaining stated motor torque characteristics and for limiting current. During starting period, it cuts out successive one or several resistors provided in the rotor circuit... - V N Prajapati
Recently, attention has been given to the identification of the instantaneous value of the rotor resistance while the drive is in normal operation... - P V Narendra Kumar
Energy conservation is nothing but a strategic use of energy in order to reduce the energy requirements per unit output. Energy conservation in domestic sector is a good point to start as about 20 to 30% of the total energy generated is utilised for domestic purpose, which is a considerable share... - Vishal Kumar Gaur & Bhavesh R Bhalja
Motorized fluid handling machinery such as air compressors and pumps consume nearly 40 to 60% electric power used by the industry. A large number of such systems installed in our process and power plants, either operate under degraded efficiency conditions due to service induced deterioration of the equipment – or operate far from the optimal operating point on the characteristic curve due to over design or mismatch with the demand or process requirements… - Dr G S Grewal, Bhavesh Vasiyani
The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied... - Kaushal K Jaiswals, Parikshit Kumar, Dr A K Bhardwaj
