Enertia Engineering Ltd., an electrical equipment company, is pleased to announce that after 2 years of R&D and commercialization, its EnerPulsar anti-islanding protection system is now commercially available in North America. Enertia is offering a free trial unit to each utility in North America to test the system within their network. A limited number of units is available, and for a limited time. EnerPulsar uses a centrally located signal generator to provide a unique signal over the high-voltage interconnecting utility lines. Fail-safe signal detectors installed at each nearby distributed generator monitor the line to detect the signal. Absence of the signal ensures the DG is isolated quickly until such time as electrical system emergency is dealt with and the signal can be restored. (The primary goal of anti-islanding protection technology is simple: safety. When a transmission line is broken, or a fault occurs somewhere in an electrical system, the local utility needs to isolate the emergency location, and ensure no power flows to it. This is straightforward for the utility-controlled generators, but can be very difficult for the utility when there are small third-party generators connected to the grid.)
