• OSI’s GIC Transducer Measures DC in the Presence of Higher AC Currents

    Jan 27, 2021
    OSI GIC DC Current Transducers help provide FERC compliance against Geomagnetic Pulse Threats. These transducers have a unique ability to measure, detect, and provide early alerts for DC current surges that can take down AC transformers. GIC transducers provide accuracte DC measurement within higher AC currents, can capture rising DC currents in transformer neutrals and can help you examine output power quality of inverters.

  • How Do You Achieve & Assure Accurate DC Current Measurements?

    Jan 8, 2021
    This short video explores the challenges and various factors that impact accurate DC current measurments. Unfortunately, most specifications do not account for the varable environmental conditions across the entire range of operation. OSI has created a powerful tool called the Visual Accuracy Calculator that provides a heat map visualization of your transducer across its entire range of operation. READ MORE

  • Monitoring GIC (Geomagnetically Induced Currents), Hall Effect Sensor

    Nov 12, 2019
    The GIC Hall Effect Transducer operates over a wide dynamic range and maintains low-level accuracy even after a large over-range. The GIC's inherently low residual effect eliminates the need to degauss in all but extreme circumstances. The split-core enclosure, with captive hardware and outdoor rating, makes installation easy and does not require circuit interruption. READ MORE
