This paper proposes a novel transmission line protection scheme based on frequency-domain model identification method with distributed parameter. Integrated impedance is defined by voltages and currents of two end terminals of transmission line. By analyzing the frequency-domain expressions of integrated impedance in internal and external fault states, the amplitude-frequency characteristics of the...
Laser interferometry is a well-established technique that is widely used in industrial and laboratory environments to measure displacement, velocity, vibration, and distance. Recently, a new technique based on self-mixing (or feedback) interferometry has been introduced. The operation of this technique is based on a feedback loop controlling the laser pump current. The characterization of the vibrometer...
