Study of Inrush Current

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…

Energy Conservation

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

Improving Energy Efficiency

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 

GSM Based Stepper Motor Control

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
