In modern power systems, the efficiency of transmission lines directly affects overall grid performance, operating costs, and reliability. Since transmission losses primarily occur due to conductor resistance and reactive power flow, engineers must carefully evaluate both design and operational strategies to minimize these losses. Below is a detailed technical review of methods to improve transmission…

How do you select cable size for a motor or load
Selecting the right cable size is important for both safety and efficiency. An undersized cable may overheat, cause voltage drops, or even lead to fire hazards. An oversized cable increases cost unnecessarily. Cable size is selected based on the following key factors: Current Carrying Capacity (Ampacity): The cable must handle the full-load current of the…
Difference between MCB, MCCB, ACB, and VCB
MCB, MCCB, ACB, and VCB are most common types of Circuit breakers. Circuit breakers are essential devices that we use to protect electrical systems from faults and overloads. They come in different types depending on the application, voltage level, and breaking capacity. MCB (Miniature Circuit Breaker) MCCB (Moulded Case Circuit Breaker): ACB (Air Circuit Breaker):…
Technical Interview Questions for Electrical Engineers
Breaking into the electrical engineering field requires not only strong academic knowledge but also practical awareness of how systems work in real projects. Whether you are preparing for a substation, OHTL, UGC, or utility-based role in Saudi Arabia and the Gulf, these 25 commonly asked technical interview questions will help you sharpen your fundamentals. Q1….
Feeder Protection Signaling
High-voltage power systems like 380kV transmission lines are the backbone of modern grids. They carry electricity over long distances, and any fault (like a short circuit or flashover) the system must detect it instantly and isolate it to protect equipment and keep the grid stable. That’s where feeder protection signaling comes in. In this post,…
The Future of Electrical Engineering: Trends Shaping the Next Decade
Electrical engineering is entering its most transformative era in decades. While the last few decades were dominated by advancements in software, IT, and telecommunications, the coming years will be defined by energy innovation. As the global demand for reliable, sustainable, and intelligent power systems accelerates, electrical engineers will be at the heart of this transition….
Data Structures in C++
Learning data structures in C++ is one of the most important steps for anyone looking to become a skilled programmer or software engineer. Data structures provide systematic ways to store and organize data, making programs faster and more efficient. With C++, you can implement data structures in two powerful ways: by building them from scratch…

Role of Synchronous Condensers in Modern Power Systems (2025)
As power systems around the world transition to renewable energy sources, grid stability has become one of the biggest challenges. Traditional generators provided inertia, reactive power support, and fault current contribution. With renewables like solar PV and wind (which use power electronics), these services are reduced. That’s where synchronous condensers come into play—an old technology…
SEC Standards Update: New vs Old
Saudi Electricity Company (SEC) has issued new standards that mayl soon replace the old ones. These updated codes are essential for engineers, consultants, and contractors working on substations, OHTL (Overhead Transmission Lines), and power system projects in Saudi Arabia. Key Points to Remember: Our Most Read Posts In the old SEC standards, the first letter…
