200 Types of Engineering Disciplines

Different Types of Engineering Disciplines

Engineering is traditionally categorized into six primary branches: biomedical, chemical, civil, electrical, materials, and mechanical engineering. Beyond these foundational disciplines, hundreds of specialized subfields have emerged, bringing the total to over 200 distinct areas of practice.

Major Equipment Used in an Electrical Substation

Electrical substations play a crucial role in transmitting and distributing electrical power. They serve as intermediaries between high-voltage transmission lines and lower-voltage distribution lines. Here are some major equipment commonly found in electrical substations:

Magnetic contactors are a form of electrical relay found on most electrically powered motors. They act as a go-between for direct power sources and high-load electrical motors in order to homogenize or balance out changes in electrical frequency that may come from a power supply, as well as to act as a safeguard.

Ancient Electricity Generation and Using Procedure

Herein this article will try the understand the history of the first electricity evaluation and ancient electricity generation procedures and the uses of electricity. We also introduce our-self to Bagdad Battery.

Amazing High Voltage Power Line and Health Risk

⚡ Are High Voltage Power Lines a Risk to Human Health?

Background: The Debate Over EMF Exposure

Concerns about electromagnetic fields (EMFs) and their impact on human health first gained attention in 1979. Since then, scientific debate has continued without a clear consensus.

• 👨‍🔬 One group argues that prolonged exposure to residential power lines may increase the risk of cancer in children and young adults.

• 🧪 Another insists that ambient EMF levels are too weak to pose serious health threats.

Despite extensive studies, definitive evidence remains elusive. Nonetheless, numerous articles suggest that high-voltage transmission lines may contribute to health issues ranging from headaches and skin disorders to cancer.

Lightning Protection Devices

The lightning protection device is by means of modern lightning and other technology to prevent electrical equipment from being struck by lightning. Lightning protection equipment can be divided into lightning protection, lightning protection socket, antenna feeder protection, signal lightning protection, lightning protection test equipment, measurement, control system lightning protection, and earth pole protection.

According to the principle of sub-field lightning protection and multi-level protection according to the IEC (International Electrotechnical Committee) standard, B-level lightning protection belongs to the first-level lightning protection device, which can be implemented in the main distribution cabinet. building; Class C belongs to the second level lightning protection device, used in the sub-circuit distribution cabinet of the building; Class D is a third-class lightning arrester, which is precisely mounted on the front end of critical equipment for safety.
