🔔 Утвержден новый национальный стандарт ГОСТ Р 71879-2024 для релейной защиты
Ключевые положения стандарта включают методы расчета времени до насыщения измерительных трансформаторов тока (классы точности 5PR, 10PR, TPY, TPZ, TPE) при коротких замыканиях.
Документ поможет: - выбирать устройства РЗА при создании новых или модернизации существующих систем; - проверять правильность работы защит в переходных режимах.

This ability to mix the public and the private, as well as the ability to use bots to engage with users has proved to be problematic. In early 2021, a database selling phone numbers pulled from Facebook was selling numbers for $20 per lookup. Similarly, security researchers found a network of deepfake bots on the platform that were generating images of people submitted by users to create non-consensual imagery, some of which involved children. What distinguishes the app from competitors is its use of what's known as channels: Public or private feeds of photos and videos that can be set up by one person or an organization. The channels have become popular with on-the-ground journalists, aid workers and Ukrainian President Volodymyr Zelenskyy, who broadcasts on a Telegram channel. The channels can be followed by an unlimited number of people. Unlike Facebook, Twitter and other popular social networks, there is no advertising on Telegram and the flow of information is not driven by an algorithm. "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read."
