This project deals with term Power Quality and its reference to terms Voltage and Current Quality, Continuity of supply. For long time the main concern of consumers of electricity was the continuity of the supply, i.e. the reliability. Nowadays consumers want not only reliability, but quality too. Power quality is determined by ability of customer equipment to perform properly. The reason to explain the current interest in power quality is growing economic impacts on the network operators (i.e. the utilities) and their customers.


The devices and equipment being applied in industrial and commercial facilities are more sensitive to power quality disturbances than equipment applied in the past. The whole system is as sensitive as the most sensitive equipment. Malfunction of equipment or misoperation of an important process can affect production continuity resulting in material damages.


We have designed a project to monitor all these things all the time because human effort is not sufficient and also not possible 24 x 7. AT89S52 is our controller, current sensor and voltage sensor are used to monitor the power supply. The details will be updated in the web server through IoT module connected to the controller. Any disturbance can be identified easily and necessary measures can be taken immediately to avoid further loss.


This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
