PQ Analysis: Undervoltage, Overvoltage, Sags, Swells

Published by testguy, November 23, 2019. Website: testguy.net Undervoltage, Overvoltage, Sags, Swells The second most simple type occurs when voltage at the load drops below a minimum rated voltage or climbs above a maximum rated voltage for some period of time. Depending on how long these conditions last, they may be referred to as undervoltage or overvoltageContinue reading “PQ Analysis: Undervoltage, Overvoltage, Sags, Swells”

Part 5: AC Power Distribution Systems & Standards

Published by Nikola Zlatanov* Medium Voltage Equipment Surge Protection Considerations Transformers If the voltage withstand/BIL rating of the transformer is less than that of the switchgear feeding the transformer, surge protection is recommended at the transformer terminals, in line with established practices. In addition, consideration should be given to using surge arresters and/or surge capacitorsContinue reading “Part 5: AC Power Distribution Systems & Standards”
