remote motor star delta starter with dry run and single phasing preventer cct diagram

The Star/Delta starter is generally manufactured from three contactors; and electromechanical timer and a thermal overload for operating a 3 phase motor at 440 volt at ac mains supply 50 Hz. The interlocking arrangement of all the contactor coils is traditionally wired in 440 volt AC.

This project uses a system to start a 3 phase motor at 440 volt AC mains supply 50 Hz with a set of 12 volt DC relays in star mode first and then to delta mode by an electronic ....etc

This socket supplies the appliances with power when the user turns them on. When the user turns them off,this socket shuts the electric power off and reduces the standby power to zero.This can be a solution to electric home appliances
drawing standby power when they are plugged in.The design uses an MCU which receives signals from a PIR sensor which detects the user when approaching the socket and the appliances. A power detector provides an MCU to control the
SSR On/Off when used as an appliance switch for shutting off the standby power.The ....etc

Authentication plays a very critical role in security-related applications like e-commerce. There are a number of methods and techniques for accomplishing this key process. In this regard, biometrics is gaining increasing attention these days. Security systems, having realized the value of biometrics, use biometrics for two basic purposes: to verify or identify users. There is a number of biometrics and different applications need different biometrics. Biometric is the most secure and convenient authentication tool. It can not be borrowed, stol ....etc

Stand-by POWER loss preventer


introduction

Stand-by power loss preventer is a device which prevents the power during when the system is on stand-by mode. It is based on the principle of electromagnetic induction (EMI is used to activate and de-activate the circuit). It mainly works on the CRT(cathode ray tube).

Working

The circuit senses high-energy electromagnetic radiation from the CRT monitor when it is on . A relay coil (L1) connected between inverting pin ....etc

Abstract In other to save energy, several countries recently made laws related to standby power consumption. To success this exertion, we should consider not only power reduction of consumer electronics itself but also efficient automatic control in networked home environment. In this paper, we present a design approach and implementation result of control mechanism for standby power reduction. Proposed mechanism has the Host-Agent based structure and uses the IEE 802.15.4 based ZigBee protocol for communication and security between Host and A ....etc
