Substation Maintenance II and Protection

Introduction

This course is the next step after Substation I to enhance the skills needed to perform all substation tasks including a focus on common transformer configurations. It offers training on the components of power and distribution type transformers, including common insulating and cooling mediums and explains common transformer configurations.

Objectives

    Upon completion of this course, the participant should be able to:

    • Explain the configuration and function of common equipment found in a substation.
    • Identify components of power and distribution type transformers, including common insulating and cooling mediums.
    • Describe and carry out AC tests performed on transformers.
    • Perform a nameplate exercise and calculate the turns ratio of transformer wiring
    • Summarize ASTM requirements for testing and sampling gas and oil in transformers.
    • Outline storage battery maintenance.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

This hands-on course is intended for apprentices, technicians, and engineers responsible for the maintenance and testing of industrial and utility substations.
