Fault protection in power systems (PS) is very essential and vital for reliable performance. It is said that a power system is defective when an undesirable condition occurs in that power system, where the undesirable condition could be short circuits, overcurrent, overvoltage, etc. The power transformer is one of the most significant equipment in the electrical power system and the transformer protection is an essential part of the overall system protection approach. Transformers are used in a wide variety of applications, from small distribution transformers that serve one or more users to very large units that are an integral part of the bulk feed system (Anderson, 1998, P.673). On the other hand, with increasing population and its unavoidable demands, it leads to high demands for increased electric power. With this increase in energy demand, existing systems can be overloaded. Overload at the end of the consumer appears on the transformer terminals, which can affect its efficiency and protection systems. One of the reported damages or tripping of the distribution transformer is due to thermal overload. To avoid transformer damage due to overload from the consumer end, it involves overcurrent trip control of the distribution transformer. Where the technology of the day has given the opportunity to use the latest trends, and microprocessor, microcontrollers are one of the requirements of the day to apply in the transformer remote protection.
In the modern era, PLC automation has been placed on the reliability of power and economy. A power transformer is a very valuable and important link in a power transmission system. Monitoring is essential to evaluate transformer performance and safe operating conditions. The high reliability of the transformer is essential to avoid disturbances in power transmission. Due to the wide range of PLC automation, various types of power transformer failure can be detected and diagnosed using the PLC system. Some articles show that transformer protection is a challenge for researchers. The work of Rohan Perera discusses the applications of protection of the transformers in line where a transmission line of the energy system ends in a transformer and a single zone of protection includes both the line as the transformer.
A high quality power transformer properly designed and supplied with suitable relays and protection monitors is very reliable. When a transformer of an electrical substation fails, the damage is usually severe due to the high power capacity. The ultimate goal is to minimize the response time after the failure. V. Thiyagarajan & T.G. The role of Palanivel presents an innovative design to develop a system based on the AVR microcontroller that is used to record the voltage, current and temperature of a power transformer in a substation and to protect the system from any uncertainty conditions. Reference research work has been done on the fully automated system based on GSM in power transformer. Operating a power distribution system with an out-of-service transformer is always very difficult. The impact of a transformer failure is more serious than a cut of the transmission line. There are several types of faults that occur in the transformer. These faults are mainly internal and external faults of the power transformer. The main concern of this role with transformer protection is to rescue the transformer against internal faults as well as to ensure the safety of the protection scheme for external faults. Overloading the power transformers beyond the classification of the nameplate can cause an increase in the temperature of both the transformer oil and the windings. Overloading is nothing more than an overload failure that occurs on the secondary side of the distribution transformer. If the increase in the winding temperature exceeds the transformer limits, the insulation will deteriorate and may fail prematurely. Faults in the power system external to the transformer zone can cause high levels as well as low voltage level in the transformer. This leads to an overvoltage fault and a lack of voltage.
