Advanced electronic voltage regulators offer a superior voltage stability solution by combining high-speed sensing, power electronics, and energy storage.What is voltage sag?One of the most prevalent and disruptive power quality issues is voltage sag—a short-duration reduction in RMS voltage, typically ranging from 10% to 90% of the nominal voltage, lasting from a few milliseconds up to several seconds.
What is the best way to address voltage sags?The best way to address voltage sags is by determining if a piece of equipment is more sensitive to voltage dips and implementing Active Voltage Correction. This can help prevent any further damage or wear to the equipment. To prevent any further damage or wear to your equipment, it is crucial to detect and isolate individual pieces of equipment that appear more sensitive to voltage sags.
How effective is voltage sag mitigation?Traditional mitigation methods, such as uninterruptible power supplies (UPS) and voltage regulators, offer limited effectiveness, particularly in dynamic and high-power applications. This has led to the exploration and development of more robust and fast-acting solutions for voltage sag mitigation.
What happens during a voltage sag?During a voltage sag, there is continual wear on PLCs, boards, line equipment, motors, lasers, and process equipment. The irregular weather pattern over a certain area puts a significant strain on the electrical grid system, resulting in considerable spike in amperage due to the low voltage. The chart below explores the physical results of voltage sag activity.
