A Critical Review of Harmonics and Mitigation Techniques in Power Systems
Abstract: The application of nonlinear loads in electrical power systems has increased significantly in recent years. These include variable speed drives (VSDs), uninterruptible power supplies (UPS), industrial rectifiers, welding machines, fluorescent lighting systems (Electronic ballast), computers, electronic appliances and other equipment with switched mode power supplies (SMPS) all of which have nonlinear voltage-current characteristics and produce harmonic distortions on the power system. Power system reliability and normal operation of electrical equipment …

Design and Testing of Transformer Protection System in Substation
Abstract: This study proposes a methodology and guidelines for distribution engineers to show that by testing and auditing of DTs, a generalized computer program is used to evaluate any given DTs system. This results in improving the stability as well as energy handling capacity of the system at minimum cost. A distribution network is selected for rehabilitation on the basis of certain planning criteria such as voltage drop, power loss equipment …

Online Server Based Monitor and Control of Industrial System Using PID with Coding
Abstract: In this system having heater mechanism with thermocouple, thermocouple will sense the temperature and will give the data to delta controller (after analog to digital conversion). After that, digital controller passes the data to PLC controller through RS-485. PLC programming will result in when temperature is low, heater will start and buzzer blows when limit exceeds, as well as when temperature is low, the heater will start again and the …

SCADA-Based Multi-drilling Mechanism by Using Sensors and Logical Operation
Abstract: Our project is auto conveyor system for industrial application by using multi-drill mechanism with PC screen control. The multi-drilling machining process is proposed for a cycle of drilling. The cycle process starts when the start switch is pressed; if the linear motor is put in place of the drilling head, in home position and then the rotary drill is rotated to bring the first work pieces to desired position. Keywords: …
