Starting the working principle of relay protection device
Protection relays mainly work on the two basic principles such as; electromagnetic attraction and induction. A protective relay is an intelligent electrical device designed to detect faults in power systems and initiate corrective actions such as tripping a circuit breaker. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. The objective of this presentation is to convey a basic understanding of protective relays to an audience of engineers already familiar with low voltage protective device coordination. Fundamental concepts and terminology will be taught using the electromechanical overcurrent relay as a foundation. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers.

Working principle of Raman optical transducer amplifier
These devices utilize the principle of stimulated Raman scattering to amplify optical signals. Typically, the Raman gain medium comprises optical fibers, bulk crystals, waveguides in photonic integrated circuits, or cells filled with gas or liquid. Raman amplification / ˈrɑːmən / is a way of increasing the signal strength in an optical fiber. The basic principles for SRS are as follows: If weak signal light and strong pump light are transmitted along a. Raman amplifier is a well-known amplifier configuration. This amplifier uses conventional fiber (rather doped fibers), which may be co-or counter-pumped to provide amplification over a wavelength range which is a function of the pump wavelength.
