This is a technical project write-up design and construction were carried out by me with deep intensive and extensive research work under the strict supervisor of Engr K.C Ugwu. I all give credit to the authors of the textbooks whose I referred to in the cause of writing this project and its subsequent design and construction. In this project, I shed light on the basic principle of operation, the design and construction procedure. Crit […]
The project presents here is on design and construct a single phase auto-transformer of rating 1kva, and step down voltage of 240v and voltage taps of 120, 48, 24v, 12v. An autotransformer is an electrical transformer with only one winding. In an autotransformer portions of the same winding act as both the primary and secondary. The winding has at least three taps where electrical connections are made. Autotransformers have the advan […]

This work is on 220vac to 110vac power supply using transformer, which served as a step down transformer whose secondary voltage is less than its primary voltage. It is designed to reduce the voltage (220v) from the primary winding to 110v in the secondary winding. As a step-down unit, the transformer converts high-voltage, low-current power into low-voltage, high-current power. The larger-gauge wire used in the secondary winding is n […]
In this project “microcontroller based automatic coil winding machine" mainobjective is to bring out a machine which can implement the idea of automation in Transformer winding or any type of coil windings. The proposed system controls the speed of a winding machine in order to obtain the optimum stop point in terms of security and fast production. The system is based on a microcontroller and an extremely simple hardware. The system ha […]
ABSTRACT Temperature monitoring system for power transformers submerged in oil applied preferentially in transformers submerged in oil and it presents several facilities in the sense of becoming temperature monitoring more reliable and safe, with highlight for the redundant measurement of temperature of the top of the oil; self-calibration of the temperature measurement entrances by means of internal references and specific electro […]
ABSTRACT This work is on 220vac to 50vac step down transformer. A Transformer is a static apparatus, with no moving parts, which transforms electrical power from one circuit to another with changes in voltage and current and no change in frequency. There are two types of transformers classified by their function: Step up Transformer and Step down Transformer. In this work we are looking at a step down transformer whose secondary volta […]
