|MEWOI AC Current Sensors(107,108,140,168 and 200 series) are sprit type current sensor with various utility, high reliability and cost-performance for current measurements and controls. |
It is possible to get the current data and interface to the circuit with simple clamping of the conductor by CT(current transformer).
These sensors are applicable for leakage current measurements,load current measurements,power measurements and metering etc.
The sprit type AC current sensor is the current transformer with ratio of ”n:1“ for the input current to be measured,when the secondary wound coils are ”n“ turns.
However,when the core material of CT is saturated by the over current flowing to the conductor, the linearity of secondary output current will be distorted and or the error of phase angle will be caused.
