1.6.12. In AC networks above 1 kV with an isolated or grounded neutral through an arcing reactor, in AC networks up to 1 kV with an isolated neutral and in DC networks with insulated poles or with an isolated midpoint, as a rule, automatic insulation monitoring must be carried out, effective on a signal when the insulation resistance of one of the phases (or poles) drops below the specified value. with subsequent control of voltage asymmetry using an indicating device (with switching).

It is allowed to control the insulation by periodic voltage measurements in order to visually control the voltage asymmetry.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Stereo audio subsystem LM4934 Boomer 30.01.2006

NATIONAL SEMICONDUCTOR Corporation announced the release of the LM4934 Boomer stereo audio subsystem, the industry's first subsystem to integrate both digital and analog inputs for multimedia and Internet telephones.

The subsystem includes a digital input, three analog inputs, audio amplifiers with controlled gain. Power amplifiers are also available: with a power of 500 mV for driving an 8-ohm loudspeaker and with a power of 30 mV for driving headphones. The microcircuit is produced in a miniature package with dimensions of 3,3x3,9 mm.
