The transformer is a static device, which converts energy from one level to another level. The objective of the project is to protect the transformer under overload conditions by burden sharing. Due to transformer overload, efficiency drops and windings overheat and burn. Thus, when the load is shared in the transformer, the transformer is protected. This will be done by connecting another transformer in parallel through a microcontroller. The microcontroller compares the load on the first transformer with a reference value. When the load exceeds the reference value, the second transformer will share the additional load. Therefore, the work of two transformers efficiently and damage is avoided. In this project three modules are used to control the load currents. The first module is a detection unit, which is used to detect the load current and the second module is a control unit. The last module is the microcontroller unit and will read the analog signal and perform some calculations and finally give the control signal to a relay. A GSM modem is also used to inform the control station about switching. The advantages of the project are transformer protection, uninterruptible power supply and protection against short circuits. When a low voltage supply system is designed for large supply load currents, parallel lower current modules are often preferred over a single large power converter for several reasons. These include the design and manufacturing efficiency of standard modular converters that can be combined into any number required to meet a given load requirement and improved reliability achieved through redundancy.
