GW-30 Flexible Rogowski Coil Current Sensors for Precise Measurement

The GW-30 is a new generation of flexible Rogowski® coil KIT current sensors that are particularly well suited for use in combination with meters.
When the current line passes through the coil at a certain position, the accuracy level of the coil reaches 0.5S level.
That is, as long as the position of the current line is fixed, the ratio difference and angle difference in different current ranges in the Rogowski coil will meet the requirements of Table L.2:The linearity of the coil is good, and the primary and secondary side transformation ratios have good consistency in
the entire current measurement range. The linearity error (ie, the maximum deviation between the actual measured value and the fitted straight line (Δymax)) is consistent with the full-scale output (y ) is required to be 0.1%. When the coil is output to the meter for sampling, there is a DC component, that is, a noise floor that presents an envelope. It is required to be ≤0.1mV to avoid noise interference from affecting measurement accuracy.
