Generally, a Bidirectional rotation of an induction motor with a remote control is a device that used to control a single phase ac motor rotation in the directions of clockwise and anti-clockwise. In straightway, we cannot turn the single-phase ac motor in both directions as well as we can only control this motor with a single phase one way switch. In other words, if we want to manage the motor in both directions then we must use any kind of motor drive, which could be so expensive, but it would also function with single phase one way switch. On concentrating these problems, here we have implemented a device that is named as a bidirectional rotation of an induction motor with a remote control device.
One of the major problems in power system is the losses occurring during the transmission of electrical power. The loss of percentage during the transmission is approximated as 26%. The main cause for power loss during transmission is the resistance of wires used in the grid. According to WRI (world resource institute), the electricity grid of India has the highest percentage (27-40%) of power transmission losses in the world. For this reason, Telsa has proposed methods of electricity transmission using an electromagnetic induction method.
The Serbian scientist “Nikola Telsa” was the first one to research and propose the concept of wireless power transfer in the year 1899, since then many scientists have been working to make his vision a reality. In the same year he has continued research on wireless power transmission in Colorado Springs and writes, the inferiority of the induction method would come into view immense as compared with the distributed charge of ground and air method. In the year 1961, William C. Brown publishes an article exploring possibilities of microwave power transmission. In the year 2009, Sony shows a wireless electrodynamics induction powered TV set.
Nowadays, street light systems in the major cities are growing quickly. The important considerations in the various technologies like electrical and electronics are cost-effective, automation and also power consumption.There are various types of street lighting systems are implemented to maintain and control the lighting systems. These are used to control and reduce energy consumption. The street light controlling is one of the main developing systems in India to save the energy. This article shows the streetlight glowing system detecting the vehicle movement.
Power saving using time operated programmed industrial load controlling system is a reliable circuit that takes over the manual task of a switch on/off the electrical devices with respect to time. It uses real-time clock (RTC) which tracks the Real Time. When this time equals to the programmed ‘ON’ time, then the corresponding Relay for the device is switched ON and then OFF as per the ‘OFF’ time that finally switches the load ON or OFF. Multiple ON/OFF times the entry is the biggest advantage of this project. Matrix keypad helps to enter the time while relays used with relay drivers for the loads.The complete circuit has its onboard power supply.
Solar energy is changed into a current by using PV (photovoltaic) cells. Throughout the daytime, the energy keep within the batteries is used to run the pump for agriculture. This project aims at developing a controlled charging mechanism providing protections for overcharge condition, deep discharge condition and below voltage state of the battery. This planned system is comprised of a solar water pump that reduces the utilization of inverters etc, so reducing the price of the project. Using the charge-controlled mechanism; the pump is operated at four totally different time slots. Difficulties like shifting the pump ON/OFF manually are overcome using this project.
There exists an intrinsic real clock (RTC) that keeps chasing the time and so switches ON/OFF the pump consequently. MOSFET’s are utilized by the charge controller as power semiconductor switches to confirm cutting off the load (DC Pump) in conditions like low battery or overload, while, the junction transistor is employed to bypass the solar power to a dummy load whereas the battery gets absolutely charged. So the battery is shielded from obtaining overcharged.
