Fault Current Limiter and Their Types
Using automation Introduction to Fault Current LimiterIn recent times, with the surging demand for energy, robust development in power generation and transmission has gained significant importance and has become a fundamental necessity. However, in any power generation system, short circuits pose one of the most persistent and challenging problems, and their impact is intensifying as the scale of generation expands. The issues caused by short or fault currents are multifaceted: Thermal Stress on Equipment: Unbea

Medium Transmission Line
Using automation A transmission line is classified as a medium transmission line when its length exceeds 80 kilometers but remains below 250 kilometers. Along such lines, electrical parameters like resistance, inductance, and capacitance are uniformly distributed throughout their entire length. Given the significant length of medium transmission lines, the charging current becomes substantial, and the shunt admittance plays a crucial role in determining the line's effective electrical characteristics.In the anal

Protective Actions to Avoid & to Reduce Electric Hazardous
Using automation General Safety Rules for EHV, HV, and MV InstallationsFor Extra High Voltage (EHV, where V≥150) kV), High Voltage (HV, with 60 kV ≤V < 150kV), and Medium Voltage (MV, having 1 kV < V < 60) kV) installations, a set of fundamental safety rules must be adhered to. These rules prioritize the physical protection of the site, carefully considering aspects such as access to equipment, as well as the basic principles governing the operation and maintenance of all electrical apparatus.Compliance

What is the difference between AC ground and DC ground?
Using automation Comparison Between AC Grounding and DC Grounding: Key DifferencesAC grounding and DC grounding may both serve to establish a reference point within an electrical system, but they diverge significantly in their fundamental characteristics, circuit behavior, and operational roles. These disparities are crucial to understand for ensuring the safe, efficient, and reliable operation of electrical systems that incorporate either alternating current (AC) or direct current (DC) power.AC Grounding Practi

Difference Between Real Ground and Virtual Ground
Using automation Real Ground vs. Virtual Ground: Definitions and ApplicationsIn the realm of electrical engineering, the concepts of real ground and virtual ground play distinct yet essential roles. Real ground establishes a tangible physical connection between the metallic body of an electrical device and the Earth, typically achieved through an Earth Continuity Conductor (ECG), Grounding Electrode Conductor (GEC), or other equivalent means. On the other hand, virtual ground is an abstract concept primarily uti

Why is the Grounding Wire Bare and Not Insulated?
Using automation Why is Mostly Solid Bare Conductor Used for Grounding Instead of Insulated Wire?A ground wire, also known as a grounding wire or ground conductor, as the name implies, is an electrical wire connected from the transformer and main panel (or distribution board) to the ground rod or earthing plate via an earthing lead buried in the ground or Earth. It is connected to all metallic parts that may come into contact with the human body to prevent electric shocks in case the hot (phase or line) wire acc
