Bergoz IPCT-2000MA Integrated Parametric Current
Elgin, IL, USA


Condition info:


The IPCT is a High Sensitivity Current sensor operating on the principle of the Direct Current Current Transducer (DCCT). Invented at CERN, the European Particle Physics Laboratory, by K. Unser in 1969. The DC component of the primary current flowing through the toroid sensor is detected by a magnetic modulator, also called a fluxgate or second-harmonic detector.
The AC component is detected by an active Hereward transformer. The two circuits are cascaded in a common feedback loop to generate a current and hence magnetic flux which always cancels the primary current flux. The IPCT output is the voltage developed by the feedback current or "compensation current" through a precision "burden" resistor internal to the IPCT.
