Electrical protection engineering has a list of favourite features which are commonly applied in distribution networks. Features such as overcurrent and conventional earth fault are ubiquitous in network protection assets, but a new list of protection capabilities is now available. Three less commonly applied protection elements which feature in the OSM Recloser system, are available […]
Voltage ride through is a common feature in power quality systems which allows equipment to continue operation (maintenance of the voltage) during voltage dips and sags appearing on the grid. However these systems do not always guarantee continued operation of variable speed drives (VSD). To overcome this, VSD sag ride-through systems have been developed. […]
Information from ABB Industrial automation has reached very high levels of sophistication. Plants, including automobile manufacturing units, chemical factories and semiconductor fabs, now house some very advanced technology which require a robust and continuous public power grid. Unfortunately, the grid is susceptible to unpredictable and erratic variation and interruption. Download the PDF document
