This manual will provide you with practical knowledge (including tips, tricks and tools) covering the fundamentals of power transformers and their testing. It will greatly assist you in communicating more effectively with your electrical engineering colleagues.
This manual also covers the importance of transformer testing and their purpose, the different kinds of transformer tests and their procedures and the practical applications of principals applied in transformer operation and maintenance.

An Introduction to Installation, Testing and Troubleshooting of Transformers
1 Introduction
There are a number of standards that define the functional and testing requirements for power and distribution transformers. For example some of the main standards available for transformers are IEC-60076 Power Transformer, BS 7821-4 parts: three-phase oil-immersed distribution transformers, 50 Hz, from 50 to 2500 kVA with highest voltage for equipment not exceeding 36 kV. BS 7844-2 parts: three-phase dry-type distribution transformers 50 Hz, from 100 to 2500 kVA with highest voltage for equipment not exceeding 36 kV, IS 2026: Power Transformers.
This manual will specify the requirements and procedure of ‘Testing of Transformers’ for Power Transformer (including auto Transformer) and will not cover small and special purpose transformers. This article mainly indicates the acceptance criterion for a transformer before putting a transformer for a particular service application, mainly relating to the testing of transformers at manufacturer’s works or in an approved laboratory. This is done to ensure that they meet the specific needs of an application.
The appeal of hydrogen fuel is that as a resource on earth it’s nearly inexhaustible. But how should engineers approach green hydrogen? If you are somewhat interested in hydrogen, green hydrogen is probably a term that you have seen floating around. Whilst the vast majority of hydrogen is produced from natural gas, green hydrogen is instead produced by the electrolysis of water. If the electric current is produced by a renewable source (e.g., wind, solar, or hydropower), the hydrogen produced is known as green hydrogen.

The textbook definition says that electrical engineering is “the branch of engineering that deals with the practical application of the theory of electricity to the construction of machinery, power supplies, and so on”. What Do Electrical Engineers Do? Because electricity is all around us, electrical engineers are employed across a broad range of industries including aerospace, defense, marine, manufacturing, power generation, transmission and distribution, resources, telecommunications, transportation, and utilities.

This Plastic Free July serves as a reminder that engineers use different polymers than those that pollute the oceans – but have a role to play in environmental management. The Australian civil action movement Plastic Free July started in 2011. Initially, the campaign included the movement’s founder and a small group from the local government in Western Australia. Now it aims to share Plastic Free solutions to help reduce plastic waste globally. Continue reading Can Engineers Go Plastic-Free? at EIT | Engineering Institute of Technology.
Biomass power production will play an important part in the sustainable energy future. So when the call came to academically contribute to sustainability, three EIT academics jumped at the opportunity. Dr Harisinh Parmar our Lab coordinator, Dr Milind Siddhpura, Course coordinator for Mechanical Engineering and Dr Arti Siddhpura a Lecturer for Mechanical Engineering penned a book chapter A sustainability case study of a biomass power plant using Empty Fruit Bunch in Malaysia.

World Ocean Day is here for us all, including engineers, to think about what we can do to protect our precious oceans. In 2022 World Ocean Day is changing. If you’re a supporter of the annual event that focuses on the ocean you would have noticed the logo changed this year, dropping the “s” from World Ocean(s) Day. Source: United Nations World Oceans Day/ YouTube The reason might seem like simple wordplay, but it digs deeper. Continue reading World Ocean Day: Dropping the ‘s’ but not sustainability at EIT | Engineering Institute of Technology.
