Description
Circuit breakers are the backbone of any power system's protection and control infrastructure. A critical component ensuring their reliable operation is thetripping coil and its associated trip circuit. This specialized course is designed to give you a comprehensive understanding of how trip circuits function, why their supervision is essential, and how to design and troubleshoot them effectively in both greenfield and brownfield substations.
Whether you are a protection and control engineer, a substation commissioning professional, or a technical trainee aiming to sharpen your fundamentals, this course will walk you through the intricate workings of trip coils, trip circuits, and supervision logic.
What You Will Learn:
Introduction to Tripping Coils
What is a tripping coil, and what role does it play in circuit breaker operation?
Energy flow and actuation mechanism behind breaker tripping.
Series and Shunt Trip Coils
Functional difference between series and shunt trip coils.
Application scenarios: Where and why each type is used in protection schemes.
Understanding the Basic Tripping Circuit
How protection relays energize the tripping coil.
Role of auxiliary relays, contacts, DC supply, and interlocks in a typical trip circuit.
Importance of Monitoring the Tripping Coil
Why it's critical to monitor the health of tripping coils in both open and closed positions of the circuit breaker.
Consequences of a failed trip coil in protection systems.
Trip Circuit Supervision (TCS) Explained
