  • What is the Energy Internet Industry

    What is the Energy Internet Industry

    The Energy Internet is a proposed framework for maximising the efficient collection, distribution, and management of energy sources using networked computing and communication systems. Its features, such as plug-and-play mechanism, real-time bidirectional flow of energy, information, and money can lead to significant benefits and innovation in electricity production and. Answering this question is at the heart of the so-called “Third Industrial Revolution,” which seeks to integrate renewable energy sources with Internet connectivity, develop digital manufacturing technology, and support green industry. In other words, the goal is to achieve sustainable production. The German Federal Ministry of Economics and Technology also launched E-Energy (Internet of Energy) about the same time. We revisit some attempts to design a digital grid similar to the internet, including packetized management of specific loads (electric vehicles.

  • What is relay protection function 59

    What is relay protection function 59

    A suffix letter or number may be used with the device number; for example, suffix N is used if the device is connected to a Neutral wire (example: 59N in a relay is used for protection against Neutral Displacement); and suffixes X, Y, Z are used for auxiliary devices. Similarly, the "G" suffix can denote a "ground", hence a "51G" is a time overcurrent ground relay. The "G" suffix can also mean "generator", hence an "87G" is a Generator Differential Protective Relay while an "87T" is a Transformer Differentia.

  • What is the working principle of a white laser diode

    What is the working principle of a white laser diode

    The working principle of laser diode centers on stimulated emission within a semiconductor junction. When forward bias voltage is applied to a p-n junction, electrons and holes are injected into the active region where they recombine, releasing photons. A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. When sufficient current flows, more electrons occupy the excited state than the ground state. A laser diode is a small semiconductor device that emits powerful and precise light using a process known as stimulated emission. These gadgets track down wide applications because of their proficiency and minimal size.
