Voltage swells can disrupt the operation of various equipment, ranging from consumer electronic devices and sensitive medical apparatus to a production/process-line of a manufacturing plant, leading to millions of dollars of industrial revenue loss. Current mitigating technologies are limited to specific power quality problems, and their wide adoption would be economically unsustainable. Faraday Grid Limited (Faraday) has developed an entirely new technology , the Faraday Exchanger – a single device, which comprehensively resolves most power quality problems and fits seamlessly into the existing infrastructure. To demonstrate the voltage swell-resolution capability of the Faraday Exchanger compared to a transformer, the Faraday team conducted laboratory experiments. For a thorough review and analysis, read this white paper.
The Power Network Demonstration Centre (PNDC), a smart grid demonstration and testing facility, carried out an independent third-party validation of the Faraday Exchanger. The tests carried out by PNDC reconfirmed that the Faraday Exchanger does offer the intended functionalities (voltage regulation, power-factor correction and power-quality control) that are beyond what can be provided by one single technology to utilities and end-users of electricity. This means that wide adoption of the FG technology will result in improved power quality and reliability, increased equipment lifetime, and reduced-capital investment in mitigation technologies. Employing the key findings from PNDC validation report, this whitepaper by Jagadeesh Gunda summarises the capabilities of the Faraday Grid technology.

The secure operation of modern electricity networks is becoming an increasingly difficult task as grids continuously employ complex interconnections, intermittent non-dispatchable renewable generation, and nonlinear loads. While these actions aim to improve power system reliability and meet sustainable energy requirements, they significantly reduce the system’s fault tolerance, inertia, and damping levels. The Faraday Exchanger (FE) technology delivers key technical and economic benefits, as demonstrated through results obtained from detailed simulations on numerous electrical networks from various countries.
When rolled out across a wider system of LV networks, the Faraday Grid technology can enable a quantum shift in energy system architecture to a new decentralised, flexible and reliable system.
Three sets of simulations measuring network performance of LV networks using conventional transformers, Online Tap Changers (OLTCs), and Faraday Exchangers were carried out to demonstrate the Faraday Grid’s superior capabilities. Read the white paper describing the simulation results via the link.

Voltage dips are the most common supply disturbances that cause interruptions in production plants.
The engineers at Faraday Grid conducted tests on RMS and instantaneous voltage signals from a conventional transformer and a Faraday Exchanger and compared the effects of a voltage dip on both signals.
