OVER VOLTAGE AND UNDER VOLTAGE LOAD PROTECTION WITH ALERT SYSTEM

Abstract :  In the paper, GSM Modem SMS Alert aims to build a system that monitors voltage and provides a breakpoint based low and high voltage tripping mechanism that avoids any damage to the load and sends a text message (SMS) to alert the user whenever the condition of under-voltage or overvoltage occurs. There is a chance of damaging electronic devices due to the fluctuations the AC mains supply. Therefore, a tripping system is required to avoid any damage to these loads. This system consists of a tripping mechanism that monitors the input voltage and trips according to limits provides. It uses 8-bit microcontroller ATmega328 with a GSM modem and 16*2 LCD attached to it externally. As soon as the input voltage falls out of the window range, it delivers an error on screen. Here, a dc motor is used as a load. This system is also configured with a buzzer that goes on as soon as tripping takes place. The states of the system are displayed on the LCD. Whenever fault occurs the microcontroller sends message to the GSM modem, then the GSM modem sends alert SMS to the user to protect their device as soon as possible.

 EXISTING SYSTEM :

 Overvoltage can occur due to single line to ground fault, which in turn will raise the voltage of the other phases. It can also cause due to disconnection of heavy industrial loads or switching on the capacitor banks. This is generally due to ungrounded or floating ground delta systems, where a change in ground reference would give voltage rise to the ungrounded system. The over voltages result because either the system is too weak for the desired voltage regulation or voltage controls are inadequate. Incorrect tap settings on transformers can also result in system over voltages.

 DISADVANTAGE :

 One major problem in industry as well as house hold is sudden over voltage or under voltage which results damage the equipment. It has cleared that of under voltage and overvoltage problem are very common and can create problem for consumer good and industrial application. The equipment in case of over voltage or under voltage and the study of over voltage and under voltage, various power quality issues.

 PROPOSED SYSTEM :

 In order to make home energy efficient we also paid attention on home devices like fans and lights .Moreover , the system also focus on outside environment such as main door , garage door and irrigation. If the thermometer feels an increase in room temperature then an electrical signal is sent to microcontroller , the microcontroller takes a necessary action like turn the fan on which work as an airconditioning. The garden of house is the place where most people stay at rest time. This system including irrigation system for the garden, in order to take care of house garden. The irrigation is done by using pump which operates on timer.

 ADVANTAGE :

 Over-voltage and under voltage protection is used to prevent damage as a result of electrical transients. It is a power supply feature which shuts down the supply or clamps the output when the voltage exceeds a preset level. Most power supplies need to use an over-voltage and under voltage protection circuit to prevent damage to the electronic components
