Relay Protection hyj
Electromechanical relays can be classified into several different types as follows: "Armature"-type relays have a pivoted lever supported on a hinge or knife-edge pivot, which carries a moving contact. These relays may work on either alternating or direct current, but for alternating current, a shading coil on the pole is used to maintain contact force throughout the alternating current cycle. Because the air gap between t. -

How to solve interference in fiber optic sensors
Some noise sources can be reduced or eliminated by proper design, shielding, or isolation of the sensor system, while others may require more sophisticated signal processing techniques to filter out or compensate for the noise. These in-fiber interferometers make use of the sensitive phase variations of waves propagating in fibers to produce intensity variations, resulting in better sensitivities compared to many pure intensity-based sensors. This chapter addresses simple optical fiber sensors based on modal interference. We give a general model of F-P interferometric optical fiber sensors including diffraction loss caused by the beam divergence and the Gouy phase shift. They have many advantages over conventional sensors, but they also face some challenges. -
