Fault Detections and Diagnosis of Electrical/ Electronic Appliances Training Requirement of Technical Colleges as a Tool for Empowering Electrical Engineering Trade Students in Nigeria

Abstract

The major purpose of the study was to investigate the fault detection and diagnosis training requirement of technical colleges as a tool for empowering electrical/electronics trade students. Two research Questions were answered. The study adopted a descriptive survey design. The population for the study was ninety two (92) comprised of all sixty six (66) electrical /electronics technical college teachers in Oyo and Ogun states and 24 electrical/electronics technologists which were sampled in the two states using purposive sampling techniques. The internal consistency of the instrument was ascertained using Cronbach Alpha method and reliability coefficient obtained for the instrument was 0.89. Structured questionnaire containing 153 items was designed and used for data collection. Mean and standard deviation were used to analyze research questions. The findings of the study revealed that ability to detect faulty components, ability to diagnose appliances components, ability to work with multiple technologies and keep up to date with new technologies are required for the training electrical/electronics students on fault detection and diagnosis of electrical/ electronic appliances in Nigeria technical colleges. The findings of the study also revealed that magnifying lens, oscilloscope, personal computer, screwdrivers, drills soldering iron, fire extinguishers, and first aid box among others are the required instrument training electrical/electronics students on fault detection and diagnosis of electrical/ electronic appliances in Nigeria technical colleges. It was recommended that necessary effort should be made by stakeholders of education and curriculum development to integrate the relevant skills on fault detection and diagnosis of electrical/electronic appliances into the curriculum of electrical/electronic students of technical colleges of Nigeria.
