Updated Designs & Additional Choices Minimize VFD Risks

摘要

Motors and variable frequency drives (VFDs) have been used for upstream oil and gas artificial lift applications (with electric submersible pumps and injection compressors) for many years. VFDs provide energy savings, process control and improvement in older well development. When VFDs were first manufacture, operators discovered that their high harmonic content and voltage characteristics shortened the motor's life by damaging the insulation system. Motor companies designed inverter-grade motors that had increased insulation systems and larger housings to dissipate the additional heat.
