  • Reclosing is prohibited in relay protection

    Reclosing is prohibited in relay protection

    Protective relay Operation: For instanta-neous reclosure, contacts must open within 10 cycles or less after breaker is tripped to insure the relay circuit is de-energized be-fore reclosing breaker. Otherwise, undesired breaker tripout occurs. The RC relay can be used for practically any reclosing scheme. Applications of the concepts to accepted transmission line-protection schemes are also presented. Many important issues, such as coordination of settings, operating times, characteristics of. Purpose: To document and implement programs for the maintenance of all Protection Systems, Automatic Reclosing, and Sudden Pressure Relaying affecting the reliability of the Bulk Electric System (BES) so that they are kept in working order. Disabling of reclosers under certain conditions is required in the "269". Auto Reclosing Scheme – It is well realized that the transient faults which are most frequent in occurrence do no permanent damage to the system as they are transitory in nature.

  • Disable SSID on Telecom Fiber Optic Router

    Disable SSID on Telecom Fiber Optic Router

    Go to your router's settings in a web browser, and navigate to the "Home/Wireless network/WLAN" page. Uncheck the option to broadcast the SSID to hide your network. This makes your Wi-Fi less visible to others, adding a layer of security and reducing unwanted connections. Remember, it's a straightforward. Nowadays, more people are using a Wi-Fi Router instead of the direct Ethernet port to connect their computers and devices to the Internet, as one internet connection can be distributed on multiple devices via a Wi-Fi Router. " However when I click on "Advanced. To improve the security of your network, you can configure your router to hide the SSID, thereby rendering it undetectable. Either ask them to put the router in bridge mode and. Disabling the SSID (Service Set Identifier) of a wireless network is a common practice aimed at enhancing security by making the network invisible to unauthorized devices.
