COURSE OVERVIEW:

The primary function of power system protection is to minimize the impact of faults by isolating the smallest possible section of the grid with maximum speed and reliability. This course provides a technical framework for "Protection Engineering," focusing on the selection, setting, and coordination of protective relays. Participants will explore the mechanics of "Fault Detection," learning how transducers (CTs and VTs) convert primary high-current events into manageable signals for decision-making logic.

The scope of this training addresses the full spectrum of protection zones, from "Generator Protection" to "Feeder Distribution." It covers the technical nuances of "Selectivity" and "Sensitivity," focusing on the coordination between upstream and downstream devices to prevent widespread outages. The curriculum provides a detailed focus on the transition from electromechanical and static technology to modern "Numerical Relays," emphasizing the role of digital algorithms in complex fault analysis.

Coverage includes the implementation of fundamental schemes such as "Overcurrent," "Differential," and "Distance" protection. Attendees will learn to utilize "Time-Current Curves" (TCC), manage "CT Saturation" risks, and understand the logic of "Breaker Failure" schemes. By combining protection theory with practical application exercises, the course equips professionals with the expertise required to design and maintain the "Silent Sentinels" that safeguard the global power infrastructure.

COURSE OBJECTIVES:

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

• Define the five "Core Principles" of protection (Reliability, Speed, Selectivity, etc.).
• Identify the "Zones of Protection" and the role of overlapping.
• Differentiate between "Primary" and "Backup" protection schemes.
• Select appropriate "Current Transformers" (CT) and "Voltage Transformers" (VT).
• Perform "CT Burden" and "Saturation" calculations.
• Configure "Inverse Time Overcurrent" (51) and "Instantaneous" (50) settings.
• Implement "Differential Protection" (87) for transformers and busbars.
• Explain the operation of "Distance Protection" (21) for transmission lines.
• Design "Auto-Reclosing" logic for overhead distribution feeders.
• Utilize "Pilot Wire" and "Carrier" protection for high-speed isolation.
• Coordinate "Protective Devices" using Time and Current grading.
• Interpret "Relay Event Logs" and "Waveform Records" for fault analysis.

TARGET AUDIENCE:

This course is intended for Protection Engineers, Commissioning Technicians, Electrical Designers, and Substation Operations Personnel.

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.
