Noise from low-voltage distribution box
This article analyzes the ten most dangerous noises in an LV substation, exploring the physics behind their generation, the risks they pose, and the diagnostic strategies required to mitigate them. In the realm of electrical distribution, low-voltage (LV) substations—typically operating at or below 1000V AC—form the critical nexus between medium-voltage distribution networks and end-user loads. While sophisticated supervisory control and data acquisition (SCADA) systems monitor voltage. Transformer noise ranks among the most persistent complaints affecting substations near residential and commercial areas. You need to know how to diagnose the fault in a low voltage distribution box safely. [pdf]
Control the access to the switch ports
To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. In today's topic we will learn about switch port mode access and how its configuration is done on Cisco switches. This can be a security risk when users connect. In the following we explain the four methods (port-based, single, multi, and MAC-based) and we illustrate the usage scenarios for each one. [pdf]FAQs about Control the access to the switch ports

Control circuit of the distribution box
This picture shows the interior of a typical distribution panel in the United Kingdom. The three incoming phase wires connect to the busbars via a main switch in the centre of the panel. On each side of the panel are two, for neutral and earth. The incoming neutral connects to the lower busbar on the right side of the panel, which is in turn connected to the neutral busbar at the top left. The incoming earth wire conne. [pdf]
