Learn power transformer protection: differential, REF, Buchholz relay, surge protection, V/Hz relays and relay settings

What you'll learn
✓ Understand why transformers require protection in power systems.
✓ Identify different types of transformer faults (internal and external).
✓ Understand the operation of transformer differential protection.
✓ Learn how current transformers (CTs) are connected in differential protection schemes.
✓ Understand biased (percentage) differential relays and their characteristics.
✓ Learn how harmonic restraint prevents false tripping during inrush current.
✓ Calculate CT ratios and relay settings for differential protection.
✓ Understand restricted earth fault (REF) protection and how it differs from differential protection.
✓ Learn how over-fluxing protection (V/Hz relay) protects transformers.
✓ Understand mechanical protection devices such as Buchholz relay, pressure relief devices, and temperature protection.
✓ Learn how surge arresters and rod gaps protect transformers from lightning surges.

Requirements
● Basic understanding of electrical engineering fundamentals.
● Familiarity with basic power system concepts is helpful but not required.
● Basic knowledge of transformers and electrical circuits will make the course easier to follow.
● Interest in learning how protection systems are used to protect power transformers in real power networks.
● No prior knowledge of protection relays is required; everything will be explained step by step.
