A MICROCONTROLLER BASED PROTECTION AND CONTROL OF A LOW VOLTAGE MOTORS BY USING ZIGBEE TECHNOLOGY

A MICROCONTROLLER BASED PROTECTION AND CONTROL OF A LOW VOLTAGE MOTORS BY USING ZIGBEE TECHNOLOGY

An induction machine plays a vital role in industry and there is s strong demand for their reliable and safe operation. They are generally reliable but eventually do wear out. Faults and failures of induction machines can lead to excessive downtimes and generate large losses in terms of maintenance and lost revenues, and this motivates the examination of condition monitoring. On condition monitoring involves taking measurements on a machine while it is operating in order…

MICROCONTROLLER BASED SPEED CONTROL OF THREE PHASE MOTOR

MICROCONTROLLER BASED SPEED CONTROL OF THREE PHASE  MOTOR

Induction motors are widely used AC motors also used in the industrial area. Advanced semiconductor technology & use of microcontroller have made the speed control of induction motor easier. The proposed paper represents variable speed control application of induction motor using v/f method. In this system, the speed of the induction motor can be adjusted to user defined speed. The actual speed & reference speed is compared & the difference is adjusted by changing the…

Implementation Of An Automatic Induction Motor Starter With Delay Using Microcontroller

Implementation Of An Automatic Induction Motor Starter With Delay Using Microcontroller

ABSTRACT It is well understood that induction motors draw higher currents during their starting operations than is the case under full load running conditions. Since the early days of induction motor availability, starting methods other than Direct-on-Line have been used, and in some cases mandated by Utilities, to reduce the effect of these high starting currents on the electrical distribution network. What is generally not recognized is the existence of short duration inrush currents, which…

GSM BASED AUTOMATIC SUBSTATION LOAD SHEDDING AND SHARING

GSM BASED AUTOMATIC SUBSTATION LOAD SHEDDING AND SHARING

ABSTRACT The aim of this project  basically is to design a system to control substation load shedding and sharing using a programmable switching control which is automatically operated. In this project we are demonstrating the working of this simple operation by using a Microcontroller. The development of this application requires the configuration of the program through the GSM module. In substation, there are many tasks like the certain loads  which needed to be switched on/off…

Low Power Three Phase Induction Motors-Star Delta Starter Using Soft Switch

Low Power Three Phase Induction Motors-Star Delta Starter Using Soft Switch

ABSTRACT This project is specially designed to provide the low voltage start to the induction motor. These can be achieved by using the star delta conversion. The Star/Delta starter is probably the common method to reduce the voltage starters in the 50 Hz industrial motor. Star delta can be used to reduce the start current applied to the motor. Therefore, a full load current is applied to the motor. It (Star/Delta)is generally manufactured from three conductors…
