Microcomputer Relay Protection Analyzer
A microcomputer protection relay tester is an electronic device designed to test digital and microprocessor-based protection relays. ZCAR-1600 microcomputer relay protection tester adopts high performance industrial PC as the control microcomputer and Windows operating system can be run on it directly. The whole process of the test and the test results are displayed on the liquid crystal display screen. The instrument has standard four phase voltage and three-phase current output. It can test not only various traditional relays and protection devices, but also various modern microcomputer protections, especially for transformer differential protection and. As someone who has been dealing with substations and power equipment for a long time, when choosing a relay protection testing instrument, the core factor is: it must precisely match the type of protection you want to test and also be compatible with the voltage level at the site. -

Fiber Optic Current Sensing Experiment
We demonstrate a Sagnac based fiber optic current sensor using only 10cm of terbium doped fiber with a high Verdet constant of 15. 5 rad/Tm at a wavelength of 1300nm. Measurements of the fiber inside a solenoid show over 40dB of open loop dynamic range as well as a minimum detectable. Aiming at the problem that the accuracy of a fiber optic current sensor is susceptible to external disturbances and temperature fluctuations, we present an adaptive technology of a fiber optic current sensor that uses the magneto-optical output signal to correct the fiber output signal. Utilizing a single-ended optical fiber wrapped around the current conductor, FOCS exploits the magneto-optic effect (Faraday effect). Explore pioneering discoveries, insightful ideas and new methods from leading researchers in the field. -
