Triol Corporation in cooperation with Especialbes completed the implementation of variable frequency drives in January 2022. Twenty-five VFDs with NEMA 3R enclosure and additional equipment were delivered. The main objective is efficient and reliable control of PSP pumps in the oilfield in Venezuela.
A few words about centrifugal pumps: they are used when boreholes to the oil basin are curved then the pumps are easy to implement and use efficiently due to their small dimensions and performance.
Regarding Triol Corporation's equipment, it is an AT24 line RT VFD with a passive filter. Why did the RT line get implemented in the first place?
This VFD has a braking resistor which in this case helps to take over the energy released when the pump rotates back in the well. When the oil is lifted, the pump operates by feeding power when the lifting process stops the oil under its weight starts to spin the pump in the opposite direction and starts to generate the power itself in this case the braking resistor takes up the released energy.
Additionally, a passive filter was built in and the filter provides a THD less than 5% on input current and less than 8% on the input voltage that meets IEEE519 requirements. Read more about Harmonics in the article
Triol Corporation is delighted to participate in such extensive and complex projects and believes in further successful cooperation with the Especialbes company.
