Insulation deterioration occurs on power system when insulators are subjected to abnormal stresses. Since insulators cannot resist indefinite amount of energy, with enough voltage applied, any insulating material will eventually succumb to the electrical pressure and electron flow will occur and once current is forced through an insulating material, breakdown of that material’s molecular structure has occurred. After breakdown, the material may or may not behave as insulator any more.
This project presents the construction of effective and efficient laboratory equipment designed to detect the breakdown of insulators when subjected to excess voltage and also to calculate the dielectric strength of insulators.
The equipment constructed incorporates a high frequency transformer to supply the different test voltages, a voltmeter to measure the applied voltage to the electrodes as well as the flashover voltage, a transistor to switch ON the high frequency transformer, a feedback circuit to maintain a stable voltage supply and an LED to indicate when a breakdown of insulators has occurred.
Also, the position of the electrodes that is the distance between the two electrodes/conductors was also considered because it helps in the determination of the dielectric strength of the insulator.
This work is split into five chapters thus: Chapter 1 deals with the general introduction of the work; Chapter 2 presents the review of the literature based on the previous information by other researchers and scholars. Chapter 3 deals with the function of the individual components of the equipment, the working principle as well as the circuit diagram. Chapter 4 deals with the main project design, testing, results and the observations while Chapter 5 presents the conclusion and the recommendations.

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONEINTRODUCTIONInsulation is the isolation between
conductors of electrical power system. It may be solid, liquid, gas or
vacuum. The insulation deterioration and its effects are two phenomena
that must be familiar with by any electrical or maintenance engineer if
adequate safety of equipment and personnel and continous service to
consumers are to be maintained.Since the introduction of electricity
in the 19th century, there has been a growing demand for electrical
energy. ... Continue reading---
