NxtPhase Demonstrates Prototype For Portable Fiber Optic CT Field Calibration

NxtPhase has developed a prototype portable fiber optic CT for use as a calibration reference which can calibrate both conventional & non-conventional CTs. The performance of the sensor is ±0.12 % scale factor error over a temperature range of -50 to +60 degrees Celsius with a dynamic range of 2 to 3600A. The phase at 60 Hz is accurate over these same extremes to ±3 minutes while the bandwidth of the sensor is from DC to 6 kHz. The sensor is configured to field calibrate any CT having either an analog voltage or current secondary & compares output from the calibration unit & the CT under test.

A powerful application, obtain the paper below for additional details.

"Monitoring Power System Networks"

By James Hrabliuk, P. Eng.
As featured in Electrical Business Magazine
(an excerpt)
 


"In an age of deregulation & major shifts in the power industry & its markets, we all search for technological advances that will help improve the efficiency of the electrical grid.

Today’s electric power infrastructure must accommodate an ever-increasing number of transactions between the centres of power generation & the countless end-users. The industry is embracing new systems, like NxtPhase optical voltage & current sensors that provide more accurate & safer measurement of power.

Thinking longer term, real-time, digital current & voltage information is a significant step toward what many refer to as the all-digital substation of the future. How is it better than conventional technology? What are the real advantages that drive utilities to move towards optic technology for measuring & monitoring their operating parameters?"
