Introduction

Designing an electrical distribution network is a complex task. Electrical engineers, panel builders, and consultants must navigate a maze of standards, perform detailed calculations, and ensure the correct selection and coordination of protection devices, all while managing tight project timelines. The traditional approach often involves juggling multiple software tools, spreadsheets, and catalogues, which can be both time-consuming and prone to error.

To meet this challenge, ABB has developed DOCweb, an intuitive, cloud-based software for creating detailed single-line diagrams of low and medium voltage electrical networks. It is the online counterpart to ABB's established DOC software, part of the larger e-Design suite, and is designed to simplify and accelerate the entire design process from a web browser. This article provides an overview of DOCweb's key features and illustrates how it can help professionals design with greater confidence and efficiency.

A Comprehensive Tool for the Modern Electrical Professional

DOCweb is a free, browser-based platform that requires only a simple registration to access. It's structured to guide the user from the initial concept of a project through to the generation of professional documentation, all within a single, integrated environment.

Key Features and Capabilities

DOCweb's toolset is built around the core needs of power system design:

Efficient Single-Line Diagram Creation: The software allows users to draw single-line diagrams using an intuitive graphical interface (CAD-like environment). It simplifies the process with features like smart filtering and guided selection, making it easy to locate and place the correct components, whether they are from ABB's extensive portfolio or standard library items. The system supports a wide variety of topologies, including radial, ring, and meshed networks.
Real-Time Calculation and Compliance: One of the most powerful features of DOCweb is its ability to perform real-time calculations. As the network is built, the tool automatically calculates key parameters like short-circuit currents, line currents, and voltage drops. It also performs built-in compliance checks, ensuring that the selected devices and cable sizes meet the requirements of local and international IEC standards, reducing the risk of human error.
Protection and Selectivity Studies: Correct coordination of protection devices is crucial for a safe and reliable electrical network. DOCweb can automatically verify that circuit breakers and fuses are properly coordinated, ensuring selectivity so that a fault is isolated without causing a wider power outage. Users can easily generate tripping curves for the protection devices in the designed network.
Comprehensive Project Documentation: From the completed single-line diagram, DOCweb can generate complete, structured reports with just a few clicks. These reports can include technical specifications, drawings, bills of materials, calculation results, and compliance details, which can be exported in various formats like DXF and PDF for inclusion in project documentation.
Scenario Simulation: DOCweb allows users to simulate different operational scenarios without needing to create new projects from scratch. For example, you can model the network when it is powered by the main transformer, by a generator, or during an outage to verify functionality and safety under various conditions.
Cloud-Based Collaboration: As a cloud-based tool, DOCweb provides seamless access from anywhere and enables easy collaboration among team members. It requires no local installation, and users always have access to the latest version of the software and its component libraries.

DOCweb in the Context of ABB's Software Ecosystem

DOCweb is part of ABB's broader e-Design software suite, which also includes the desktop-based DOC software. While DOCweb is fully functional and accessible from any browser, ABB also continues to support DOC as a more powerful offline application for complex projects, using the same robust calculation engine. The choice between them often depends on user preference for a cloud-based, accessible tool versus a more traditional, local installation.

Conclusion: A Modern Approach to Electrical Design

DOCweb by ABB represents a significant advancement in the tools available to electrical professionals. By combining powerful calculation and analysis capabilities with an intuitive interface and a wealth of product data, it addresses the key pain points of modern electrical design. For engineers and panel builders, it offers a faster, smarter, and more reliable way to create and document electrical networks, ensuring compliance and minimizing the risk of costly errors. As a free and continuously updated tool, it stands as a valuable resource for the industry.
