The Method of the Equivalent Deposit of Deposited Salt (DESD) to Determine the Contamination of the Insulation of Electric Lines in Areas of Manabita Region

Abstract

The present work is related to the quantitative determination of the environmental contamination that affects the insulators in the subtransmission electrical networks existing between the cities of Montecristi and Manta. This area is the one with the largest industrial settlement, in addition to the proximity to the sea and other road development activities that contribute to contaminating the insulators of the 69, 138 and 230 kV lines causing interruptions in the supply of electricity to various sectors of the city of Manta. That is, the types of pollution known as industrial pollution, marine pollution, desert pollution and other types of pollution that are generated by industries near the sea converge. The results of this research work ended, being able to determine the levels of contamination by means of the Equivalent Deposit of Deposited Salt (DESD) method after 12 months of monitoring of the control insulators. This method consists of obtaining the level of environmental contamination in milligrams of NaCl, capable of forming a solution whose electrical conductivity is equal to that obtained from the solution composed of the contaminant deposited on the insulator and a volume of low conductivity water used. To remove the contaminant on the insulator surface.
