In order to continuously improve the transparency of power distribution grids, it is important to have precise knowledge about the relevant conditions in the local grid. This is achieved by utilizing ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Each motor branch circuit must be protected against short circuit and ground faults by an overcurrent device sized no greater than the percentages listed in Table 430.52. A branch-circuit ...

Connecting them at only one point. Cutting the ground plane under a mixed signal component Connecting them with capacitors. Segmenting the ground plane in a PCB such that there is only a narrow ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular Microchip ...
