Bergoz Instrumentation has introduced the IPCT, (Integrated Parametric Current Transformer) for non-contact high resolution AC & DC bipolar current measurement with unequalled performance: 10 µA rms resolution on any preset factory range from +/- 1 mA to +/-5 A, with 0.1 % accuracy. IPCT is well suited for non-contact current measurement applications such as: -Low current at high voltage -Return ground current, DC and AC -Leakage current, DC and AC -Sum of low currents -Small difference of large currents -Low current at high voltage -Power tube electrode current -Electrostatic corona discharge -Electrochemically induced currents -Standby systems charging current... IPCT can withstand high overload and inrush currents. Sensitivity may be increased with multiple primary turns. The precision is 100 times better than Hall effect devices. The IPCT works on the principle of the DCCT, invented at CERN, the European Particle Physics Laboratory, by K.Unser in 1969. The DC component of the current flowing through the toroid sensor is detected by a magnetic modulator, also called fluxgate or secondharmonic detector.
