Hering VPT - Introduction

Transformers are the basic component of any industry since they enable power transmission and distribution. Since a flaw in transformers could be costly, the working conditions of transformers should be checked periodically. The insulation materials of transformers are protected by healthy transformer oils which are free from contaminants. In the absence of contaminants in transformer oil, the longevity and performance of transformers is boosted. Any industrial oil, besides transformer oil, tends to get polluted in course of time, due to chemical changes that might happen. The duration of the purification process also depends upon the contamination level. In the purification process, water content is reduced in the fluids and other materials, thereby optimizing the dielectric properties of the transformer oil. The resulting improvement in insulation boosts the transformer’s performance. Repeated operations of transformers result in oxidation of transformer oil with formation of thermal by products. These sediments cause breakdown in transformers and interrupt power supply. The transformer oil filtration system eliminates sludge which affects the insulation material of the transformer. The temperature of oil entering the filtration system is increased in a bid to remove 60 ppm moisture and the oxygen within the moisture. The first filter is designed to retain particles above 1mm size followed by another filter which does not allow particles beyond 50 microns size, to flow. Appropriate cartridges help this function after which the oil enters an ionic chamber where acid contents are eliminated. The entire process is repeated few times so that the standard quality of the oil is restored. The quality of oil before and after filtration is compared, after which the process is completed. The high vacuum oil filtration system are carefully sealed to prevent any leakage and exposure to the external atmosphere. The filtration machine is equipped with appropriate controller
