ENGINEERING ARTICLES

 Engineering has always been a field that's constantly evolving. However, with the rapid advancements in technology in recent years, the future of engineering looks more exciting than ever before. In this article, we will discuss some of the emerging technologies that are set to shape the engineering industry in the coming years. Artificial Intelligence (AI) and Machine Learning (ML) AI and ML are already making waves in many industries, and engineering is no exception. Engineers are using AI and ML to improve designs, optimize processes, and reduce costs. For example, ML algorithms can analyze large amounts of data to predict when a machine is likely to fail, allowing engineers to schedule maintenance before a breakdown occurs. 3D Printing 3D printing technology has been around for several years now, but it's only recently that it's become more accessible and affordable. Engineers are using 3D printing to create prototypes quickly and cheaply, allowing them to iterate desi...

Star-delta starters are a popular method for starting electric motors. They provide a number of benefits and can be used in a variety of applications. In this article, we will explore the advantages of using a star-delta starter for motor control, as well as some of the applications in which they are commonly used. One of the main benefits of a star-delta starter is that it reduces the inrush current when starting a motor. Inrush current is the surge of current that flows through a motor when it is first turned on. This surge can cause damage to the motor and to other electrical equipment on the same circuit. By using a star-delta starter, the inrush current is reduced, which protects the motor and other equipment. Another benefit of a star-delta starter is that it reduces the torque during the starting phase. This is important because motors can generate very high torque during the starting phase, which can cause damage to the driven equipment. By reducing the torque during the starti...

Electrical engineering is a field that has revolutionized the world we live in, from powering our homes to enabling us to communicate with anyone in the world at any time. With the increasing demand for sustainable energy and the rapid pace of technological advancements, the field of electrical engineering is ripe with opportunities for growth and development. In this article, we will discuss some of the current trends and challenges in electrical engineering and the impact they have on the modern world. One of the key areas of focus in electrical engineering is renewable energy. With climate change becoming a pressing issue, the need for sustainable energy sources has never been greater. Electrical engineers are at the forefront of developing new technologies to harness renewable energy sources such as solar, wind, and hydro power. This has resulted in a growing demand for skilled electrical engineers who can design, install, and maintain these renewable energy systems. Another area o...

When carrying out the work of cable laying in the underground transmission line, the trench is to be dug/ prepared. Trench work should be done by following safety precautions. All pits and trench work shall comply with WorkSafe requirements, particularly the WorkSafe Code of Practice: Excavation. They may include but are not limited to: When a pit is to be left open overnight, proper barrier mesh and flashing lights, etc as required or the pit must be covered. Soil must be piled safely back from the edge of the pit. Pits or trenches deeper than 1500mm in normal soil may require a ladder for access and require shoring, benching or sloping of the sides of them. Pits or trenches may require shoring if less than 1500mm deep and the soil is unstable. Undermining walls, foundations, streets or pavements are to be avoided otherwise appropriate shoring is required. All shoring, benching and sloping must be installed. Barriers shall be erected to vehicles inadvertently falling into the excavati...
