COURSE OVERVIEW:

Electrical drawings and schematics are the vital documents that describe the logic, connectivity, and physical reality of an electrical system. This course provides a technical deep-dive into the creation and interpretation of these documents, focusing on the standardized symbology and drafting conventions used across utility and industrial sectors. Participants will explore the hierarchy of drawings, from conceptual one-line diagrams to detailed point-to-point wiring schematics, ensuring they can communicate complex engineering data accurately.

The scope of this training addresses the wide variety of technical illustrations required for design, installation, and troubleshooting. It covers the technical nuances of representing three-phase power systems, control logic, and instrument loops within a single project set. The curriculum provides a systematic focus on the interpretation of device codes, wire numbering systems, and terminal representations to ensure that the user can translate a paper drawing into a physical wiring installation without ambiguity.

Coverage includes the application of international standards such as IEC and ANSI to ensure drawings are universally understood. Attendees will learn to utilize drawings as a primary tool for fault-finding, learning to trace signal paths and identify potential failure points within a schematic. By combining theoretical drafting knowledge with practical diagnostic exercises, the course equips professionals with the expertise required to manage the full lifecycle of electrical documentation in high-stakes engineering environments.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Differentiate between one-line, three-line, and schematic diagrams.
• Identify standardized electrical symbols for all primary components.
• Interpret device function numbers according to international codes.
• Trace power and control paths through complex industrial schematics.
• Understand wire numbering and terminal identification systems.
• Navigate inter-page cross-references in large drawing packages.
• Utilize drawings to identify the root cause of circuit failures.
• Distinguish between schematic logic and physical wiring layouts.
• Interpret instrument loop drawings and P and IDs correctly.
• Verify the accuracy of "As-Built" drawings against field conditions.
• Explain the role of block diagrams in conceptual system design.
• Communicate technical changes clearly using standard red-line methods.

TARGET AUDIENCE:

This course is intended for Electrical Technicians, Junior Engineers, Maintenance Personnel, and CAD Operators who work with technical documentation.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
