GridON sets the new standard for electrical grid reliability, safety, performance & efficiency

Fault Current Limiters for increased capacity in electricity networks, for reliable connection of distributed generation and renewable energy sources, and for increased supply of power and reduction of arc-flash energy in industrial plants

GridON is a leading provider of Fault Current Limiting solutions for increased capacity in electricity networks and for cost-effective connection of distributed generation and renewable energy sources. GridON provides fault mitigation solutions for network operators, independent power producers, and industrial customers.

GridON enables the ever-growing demand for electricity consumption, while improving energy efficiency and network stability, and reducing carbon emissions. Short circuit surge currents in electricity grids are creeping up with increased supply on meshed networks, often exceeding network protection capabilities. Cascading fault currents result in supply disruptions, equipment damage and severe power outages. Grid operators are forced to invest hundreds of millions of dollars in order to prevent catastrophic consequences. Conventional solutions such as grid segmentation and costly upgrades negatively impact the power quality, stability and reliability of supply.

Electricity network operators are required to increase power capacity, while keeping grid resiliency. Connection of Distributed Generation (DG) and renewable energy sources is often restricted by network operators, demanding proven means for limiting excessive fault currents. Intermittent current fluctuation from alternative energy sources has also negative impact on the network protection system. Independent power producers are often required to make significant investments and bear long delays and loss of revenues, before receiving permits to connect. 

Energy intensive industries - such as chemical processing, steel, cement, data centers, mining, oil & gas, and water desalination - rely on uninterrupted operation and are extremely sensitive to electricity disruptions, which may often lead to severe business impact and financial losses.

GridON is offering grid operators, independent power producers and industrial customers cost-effective fault current limiting solutions which enable network meshing and cost-effective connection of distributed generation and intermittent renewable energy sources; while improving network stability and energy efficiency. The product accelerates connection of new generation sources and enable secure supply of power to utility networks and industrial plants. Network planners are now able to quickly design in the product with minimal changes in the network. While eliminating costly network upgrades and early retirement of fit-for-use equipment, GridON's products can save between tens and hundreds of millions of dollars in industrial and utility networks, respectively.

GridON offers two product lines which cover all market segments; (a) a saturated-core Fault Current Limiter (FCL) for mid-high voltage distribution and transmission networks, and (b) a solid-state Fault Current Limiting Interrupter (FCLi) for low-mid voltage DG connection and industrial applications. These cost-effective solutions significantly reduce capital expenditure and time consuming labor, required for network upgrades.

Being scalable to very high voltage and power ratings, the commercial FCL product is well-suited for distribution and transmission networks. GridON’s FCLs have been operating flawlessly in live networks since early 2013; proving extremely reliable, easy to operate and maintain, and very effective in limiting numerous faults. GridON’s FCL is based on combining industry-standard, proven transformer technology with unique and proprietary concept of electromagnetic flux alteration on a saturated iron core. This fail-safe system responds instantaneously to faults, suppresses fault current for its entire duration, and recovers immediately following fault clearance – being always ready for consecutive faults. The FCL is the first commercially aviable pre-saturated fault current limiter currently available in the market. GridON has partnered with Australian based Wilson Transformer Company, a shareholder and manufacturing partner, to offer a state-of-the-art portfolio of FCL products to the market.

GridON's cost-effective compact FCLi are offered for fault current reduction and arc-flash mitigation in low-to-medium voltage networks. Designed with relatively small footprint and low price tag, the FCLi is a perfect solution for distribution operators, independent power producers and industrial customers. This solid-state based product limits excessive currents in the network before they rise to high level, and acts to interrupt the fault current before the first current peak. The FCLi controls the overall fault level in the network, allowing expedited connection of new generation sources and increased power capacity in industrial plants.

GridON has been an active member of the IEEE/PES workgroup PC37.302 which issued an official guideline for fault current limiting technologies. GridON won prestigious awards including the 2013 UK Energy Innovation Award for the Best Energy Network Improvement, the 2012 European ACES Smart Grid and the 2011 GE ecomagination “Powering the Grid” award.
