Special Display Instrument for Fiber Current Transformer

Abstract:

To meet the requirement of fiber current transformer, special display instrument was deigned. SCM and advanced signal process technology were adopted in the instrument, so that the output voltage signal of low voltage terminal can be utilized by instrument to display measured busbar current value real-time. Besides, section linearization and distinguish calibration methods were adopted to improve measurement precision of display instrument. The experiment results indicated that this instrument has virtues of reliability, high precision and low cost, importantly, it can come up to the 0.2 standard. So we can draw a conclusion that this instrument can meet the industrial requirement for display instrument.
