Abstract:This work discusses the basic principles of Voltage-Chopping and energy-saving technology for the three-phase AC asynchronous motor running in the low load conditions causing the low power factor and low efficiency. On this basis, Developed chopping control and energy saving controller for three-phase AC asynchronous motor .By real-time detection of power factor and other parameters,the energy-saving controller using PWM chopped-controlled voltage regulator means regulating the motor supply voltage to achieve … Show more

“…For a fixed amplitude of discharge current pulse, the steeper is the front of a current pulse that passes through the surge arrester, the greater is the residual voltage of surge arrester. These and other properties of the surge arresters become important when dealing with the insulation coordination and simulation of lightning protection of substations [2]. There are different mo dels of the surge arrester for circuit simulation software, both simple consisting of a single non-linear element and complex consisting of several linear and non-linear elements.…”
