How to assess the sensitivity of relay protection
An operational current at relay terminals should be observed to ensure proper sensitivity. (For high-impedance differential relays). Gradually increase the. The relay protection sensitivity is one of the determined factors in the power system, however, it is often overlooked in current distribution network (DN) planning. A single missed test can lead to the following: Digital and numerical relays require comprehensive procedures: self-test verification, digital input/output checks. The relaying equipment must be sufficiently sensitive so that it operates reliably when required under the actual conditions that produces least operating tendency.

Attenuation Principle of Passive Optical Networks
An optical attenuator is a passive device that reduces optical power in a controlled way without changing the signal format. PON system should include an optical distribution network (ODN), optical line terminal (OLT), and optical network unit (ONU). Firstly, ODN is an FTTH (fiber to the home) optical network based on PON equipment, which provides an optical transmission channel. Attenuation is a term in communication that refers to loss (reduction) in signal strength when a signal is transmitted from sender to the receiver. This loss happens due to a variety of factors. It is measured using decibels (dB). It contains optical absorption materials and is used to reduce the power of optical signals in optical fibers. for achieving a suitable signal level for a data receiver in a telecom system.
