Vacuum circuit breaker ppt

Here is a sample PPT on Vacuum Circuit Breakers:

Slide 1: Title Slide

Slide 2: Introduction

Definition: A vacuum circuit breaker is a type of circuit breaker that uses a vacuum as the interrupting medium to interrupt electrical currents.
Advantages: High reliability, low maintenance, and fast switching times.

Slide 3: Principle of Operation

The vacuum circuit breaker uses a vacuum interrupter to interrupt the electrical current.
The interrupter consists of two electrodes that are separated by a vacuum gap.
When the current is interrupted, the electrodes are separated, creating a vacuum gap that extinguishes the arc.
