Surge Protection for Electric Power Grids

Inductive Fault Current Limiters for Reliable Power Supply and Efficient Grid Operation

New performance requirements demand large scale investments to improve the infrastructure of electric power grids. Zenergy Power’s Fault Current Limiters are a cost effective solution to enhance fault tolerance and transmission capacity. The compact and easy-to-install systems protect grid components against damaging single and multiple power surges while maintaining a disruption-free downstream power supply.

• Improved operational reliability of electric power supply
• Higher grid capacity and longer lifetime of substation equipment
• Reduced investment for grid expansion
• Lower cost for integrating distributed renewable power generation into the grid
• Deferred upgrades of substation equipment

The US power utility Southern California Edison has commissioned the first Fault Current Limiter to regular operation in its distribution grid in March 2009.
