Overfrequency protection principle of relay protection
Over frequency protection is configured by applying a set point above normal operating frequency. The frequency in electrical installations must be maintained within accepted operating levels to minimize the risk of damage to motor loads, sensitive electronics, and to ensure the proper operation and performance of all loads. There are two independent protections: Under/overfrequency protection. Over frequency protection or over speed protection is used to protect the generator from over speeding of generator's rotor, reduce the eddy current losses as the frequency increases and protect the winding against v/f over fluxing protection. Normally, Generator is an energy conversion device. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. In this article, we explore what normal frequency is, what scenarios cause power system frequency to vary, and some of the common protection elements which act on these fault scenarios.

Laser Diode Marking Principle
A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple P–N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in or. OverviewA laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a device similar to a in which a diode pumped directly with electrical current can create. Following theoretical treatments of M.G. Bernard, G. Duraffourg, and William P. Dumke in the early 1960s, light emission from a (GaAs) semiconductor diode (a laser diode) was demonstrat.
