The widespread implementation of electronic equipment made voltage sags and swells as the most critical power-quality issues faced by utilities and consumers. Although several power conditioning technologies exist to mitigate voltage-sags and swells, their effectiveness is often limited to certain equipment types or power-quality disturbance profiles and their wide adoption is uneconomical. Moreover, their installation often adds further control complexity to network operation. Faraday Grid Ltd (FGL) has developed a completely new technology, the Faraday Exchanger (FE) – a single device featuring power flow control, voltage regulation, power factor correction and power conditioning capabilities. The objective of this paper is to demonstrate the power conditioning capability of Faraday Exchanger in mitigating voltage sags and swells through laboratory experiments on the device. The experimental results confirmed that the Faraday Exchanger competently limits the impact of sags and swells ensuring that they are inconsequential, thereby improving sag- and swell-ride-through performance of downstream equipment or process.
