WebinarOptical Voltage and Current Sensors
May 21, 2025 • Webex
Please mark your calendars for our upcoming webinar on Optical Voltage and Current Sensors, scheduled for Wednesday, May 21st at 1:30-3:00 p.m. ET.This presentation explores the transition from conventional oil-filled instrument transformers (ITs), typically used for metering and protection, to optical voltage and current sensor technologies. We’ll briefly cover the operating principles, performance characteristics, and integration advantages of optical sensors, alongside a comparative analysis with traditional ITs. Key adoption challenges—including interface compatibility, standardization, and utility familiarity—are discussed in the context of accelerating digital substation deployment. We’ll also highlight how optical sensors connect through merging units and IEC 61850-based substation LANs. Application examples include support for phasor measurement units (PMUs) and other digital measurement projects by NuGrid. The session concludes with use cases leveraging wideband optical measurements (up to 1 mega-sample per second) for advanced monitoring such as traveling-wave fault location, transient recovery voltage (TRV) measurements, and power quality monitoring.Presenter(s): Farnoosh Rahmatian, Ph.D., P.Eng., Fellow IEEE, founder and president of NuGrid Power Corp.
