Digital Transformer Tester HEW series CT PT Comparator

Technical Parameter

Accuracy class 2
Current range 5A, 1A
Voltage range 100V,100/√3V
Percentage Error Less 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
