380kV Gantries & Gantry Equipment
380kV Gantries & Gantry Equipment is our first post that is a part of Substation Layout Drawing & Explanation each equipment in a 380kV BSP. Gantries are the tall steel structures at the extreme ends of the yard that serve as termination points for overhead transmission lines (OHTLs) entering the substation at 380kV. In this…
Inside a 380kV BSP: Overall Layout Drawing Explained
In today’s rapidly growing power networks, Bulk Supply Points (BSPs) play a vital role in ensuring reliable electricity transmission and distribution. A BSP is essentially the bridge between high-voltage transmission lines (380kV in Saudi Arabia) and the sub-transmission network (132kV) that feeds urban centers and industrial zones. While single-line diagrams (SLDs) show the electrical connections,…
Power Transformer Testing Overview
In this post we present you Power Transformer Testing Overview as per IS:2026 (Part I). Power transformers are critical components in the electrical power system, and their reliability is ensured through rigorous testing as specified in IS:2026 (Part I) – Power Transformers: General Requirements. These tests are categorized into Type Tests, Routine Tests, and Special…
Vector Group of Transformers
Vector Group of Transformers, indicates the phase relationship also called phase difference (angle shift) between the High Voltage and Low Voltage windings. It tells you how the windings are connected (star or delta) and the phase displacement between them. This is important for ensuring proper synchronization and operation in power systems. This is our 6th post that…

This unique post about Top software programs for Electrical Engineers is for those engineers who are seeking jobs in Saudi Arabia. Mastering key software tools can significantly boost their employability, especially in industries like power generation, transmission, oil & gas, and construction. Below is a list of the top software programs to focus on: 1. PLS-CADD…
SEC announced over 16 Projects worth more than 8 billion SAR
July, August, and September have been groundbreaking yet challenging months for contractors as SEC announced over 16 BSP projects worth more than 8 billion SAR. 🚀 The pressure was immense as the typical tender preparation period, which usually spans several months, was compressed into just two to three weeks. Upto now 9 projects are closed….
Main Components of Substation-Power Transformers
In this series of Posts we are going to Explore Main Components of Substation. We will focus on a 380 kV substations or Bulk Supply Points (BSP) that are most common in Saudi Arabia. A substation is designed to manage the transmission and distribution of electrical power at high voltages. These include several key components…
Job Responsibilities of a Proposal Engineer
This is a Comprehensive Post about Job Responsibilities of a Proposal Engineer (Electrical Tender Engineer for Substation EPC Projects). A Proposal Engineer plays a vital role in the bidding process for Engineering, Procurement, and Construction (EPC) projects. Their main job is to create and submit proposals that meet client needs while ensuring that the projects…
Transmission lines design important points
In this post we are presenting to Transmission lines design important points. These points are from Saudi electricity company’s design, engineering, materials and construction standards. SEC follows their own standards for transmission, substation and Underground cables design and construction standards.These important points are taken from below Standards. Operating Areas in KSA Saudi electricity company divide…
