  • 2hp Vfd Variable Frequency Drive - USA

    price: contact company for price

    I' m about to face this exact problem and have been looking at options

    that are both economical and practical that will assist in mitigating

    VFD harmonics.

    I have a large pumping station at the end of a rural

    supply line.

    We want to install a 2hp VFD that will total in excess of 2

    hp - 11 VFDs.

    Power quality is a problem.

    We' ve looked at GoHz VFDs as

    well as active filters.

    What are you currently using or would you

    suggest we look at?

    This low frequency issue is the elephant in the room for the whole ' smart grid' with distributed generation, reactive power systems and local grid management.

    If Tesla were alive he would be horrified at what is happening to the 2hp VFD.

    Some product standards ( marine power converters is one) do cover the lower frequencies and call out limits in the 9kHz to 150kHz range.

    The IEEE have limits on this range in their IEEE1547 distributed resource standards.

    No doubt active filter manufacturers would carefully choose a product standard that makes it as easy for them as possible.
