    Phase Angle Error CT PT Test Set


    Digital Transformer Tester HEWE series CT PT Test Equipment Comparator


    Technical Parameter

    Accuracy class2
    Current range5A, 1A
    Voltage range100V,100/√3V
    Percentage ErrorLess than 1.5%*FS
    Basic Error
    When testing CT PT error & impedance & admittance, the error will not beyond:

    ΔX=±(X*2%+Y*2%+Dx)

    ΔY=±(X*2%+Y*2%+Dy)

    ΔX: basic error limit value of in-phase component

    ΔY: basic error limit value of Quadrature Component

    X: Indication absolute value of in-phase component

    Y: Indication absolute value of Quadrature Component

    Dx & Dy: Zero error and Quantizing Error

    When testing CT & PT, Dx,Dy=1(or 2)%*(Error limit value of CT & PT

    When testing Z & Y, Dx,Dy= 3 digits
