Introduction

Industrial substation maintenance involves the regular inspection, testing, and servicing of electrical equipment within substations that supply power to industrial facilities. This essential process ensures the reliability, safety, and efficiency of electrical systems critical for uninterrupted operation of industrial processes. Maintenance activities typically include checking transformers, circuit breakers, switchgear, protective relays, and other components to prevent malfunctions, minimize downtime, and ensure compliance with regulatory standards.

Objective

Substation types, applications, components and safety procedures

Medium-voltage circuit breaker maintenance and testing methods
Perform insulation resistance, contact resistance on air, oil and vacuum breakers, and tank loss index on oil circuit breaker and vacuum bottle integrity tests on vacuum breaker.
Switchgear arrangement, torque requirements, insulation systems and maintenance intervals
Perform switchgear inspection and maintenance in lab.
Battery types, applications, systems and components
Perform battery maintenance and testing in lab.

Audience

This course is intended for Electrical Engineers, Electrical Supervisors and Electrical Technicians engaged in the commissioning, testing, start-up, troubleshooting, maintenance and repair of Electrical Equipment and Control Systems. Because the methods and examples are generic, trainees from all industries, especially oil and gas fields will benefit. Participants need no specific requirements other than a good understanding of electricity and magnetism and some relevant experience.

TRAINING OUTCOME

At the end of this training Participants will be able to:

Following the attendance at this course, participants will return to their respective organizations equipped with new or refreshed skills to ensure that each power components related to the industrial substations are tested and maintained in a fashion that ensures reduced costs and or start-up delays plus identified faults or problems are repaired, and the underlying causes are identified and eliminated to reduce further failures

NOTE:

Pre & Post Tests will be conducted.

Case Studies, Group Exercises, Group Discussions, Last Day Review & Assessments will be carried out.

…………………………………………………………………………………………………….

Certificate

Define Management Consultancy & Training Certificate of course completion will be issued to all attendees.

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. You will also be encouraged to raise your questions and to share in the development of the right answers using your analysis and experiences. Tests of the multiple-choice type will be made available daily to examine the effectiveness of delivering the course.

Very useful Course Materials will be given.
