Dedicated harmonic filters for oilfield ESP applications
Series passive harmonic filters are extremely popular for oilfield ESP (electrical submersible pump) applications; in desert oilfields, offshore or installed on FPSOs.
They are renowned for their simple design, effective performance, ruggedness, both electrically and environmentally, lack of complex maintenance and ability to operate in high ambient temperatures (to 55 deg C).
Sentinel Power Quality Group and its partners have successfully supplied both ESP vendors and IOCs, since 2012, with series passive harmonic filters, output filters and high frequency transformers for land-based oilfield applications, offshore platforms and FPSOs.
