The P54x provides true, phase-segregated current differential protection. The measurement algorithm is extremely reliable, offering fast detection of internal faults and stability for external faults.
Dual-channel fiber optic current sensor based on carrier-transposed
A dual-channel fiber optic current sensor based on carrier-transposed modulation technique is proposed and demonstrated. The cross-talk between two channels is tactfully eliminated, which provides an
Dual-channel fiber optic current sensor based on carrier-transposed
In this paper, a new interrogation scheme for a fiber Bragg grating (FBG) current sensor based on a dual-loop optoelectronic oscillator (OEO) with high stability, high precision and simple...
Dual-channel fiber optic current sensor based on carrier-transposed
In this work, we present a dual-channel fiber optic current sensor based on carrier-transposed demodulation technique.
Dual-Channel Fiber Optic Differential Interferometer With Square
We propose a novel dual-channel FODI (DC-FODI) with square-wave modulation, which enhances sensitivity and improves the dynamic range compared with previous designs.
