TRANSFORMATION: Transforming DC Currents & Voltages to Measurable Values
Feb 11, 2021
DC CURRENT TRANSFORMATION. Many people arrive here looking for DC Transformers, hoping OSI has created a loophole in a few key laws of physics. Maybe what you really need is the ability to accurately transform from operating levels to signal or measurement levels while providing isolation between the two levels? READ MORE -
Challenged by DC Current Measurements?
Feb 1, 2021
There are many factors that impact the accuracy and reliability of DC current measurements. This short article examines how residual magnetism can significantly alter DC current measurements. Other factors that impact accurate measurement include, temeperature, overrange, offsets, linearity, harmonics, and the location of the sensor to what it is measuring. READ MORE -
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 -
