Electronic circuir breaker project
CHAPTER ONE INTRODUCTION 1.1. General Introduction According to (Mohankumar, 2013), “Electrical circuit breaker is a device that senses an overload and short circuit condition, then breaking the circuit to protect the system or circuit from damages or breakdown”. Circuit Breaker was invented over hundred years ago, it was first described by Thomas Edison (1900) as fuse used by his commercial power distribution. The initial reasons for developing the circuit breaker was to protect the lighting circuit wiring from impulse short-circuit and overload (Isreal, 1986). Advancement in the circuit breaker technology was done with the advance in general technology. It advancement include the modern miniature circuit breakers similar to those used currently and it was patented by Brown and Boveri over 90 years ago, (1924). As time pass, requirement for various other types were created due to advancements, for instance, the thermal magnetic breaker which is still in use till date was crea
