Electrical, Renewable Energy, Power, DCS Courses


Electrical Drawings and Control Circuits

Introduction:

This course begins with the development of various relevant drawings and symbols representing devices that are vital in all electrical installation to ensure continuity and efficient operations. The primary and fundamental tool for troubleshooting and maintenance of an electrical installation is to understand and interpret electrical drawings and ladder diagrams.

Electrical symbols, schematic, and wiring diagrams facilitate the operations of the electrical installation equipment. This program will cover all these aspects of electrical blueprint reading and the tracing of circuits. It will familiarise engineers and technicians with the various standards and practices, also, to understand the power flow and equipment installed. As fitted diagrams and ladder diagrams will we presented to correlate with the electrical equipment installed. Tracing of electrical circuits with the relevant wiring diagrams will be demonstrated to ensure correct methods of troubleshooting
