A reliable power supply is based on power transformers that function efficiently. Yet many systems in the USA have been in service for a great many years and are therefore prone to faults. Further risks to grid stability include environmental disasters and violent attacks on substations.
Power transformers equipped in this way are flexible in their use and easy to transport, enabling them to be used as emergency transformers. This means that damaged transformers can be replaced within a very short time.
PFISTERER’s first CrossPower system was put into operation in Lithuania at the start of February. The hybrid energy management system enables even remote regions to receive a reliable and stable supply of energy using regenerative sources.
Forecasts predict that there will be 27 megacities with over ten million inhabitants by 2020. Energy requirements will continue to rise in the world’s major hubs while the amount space available for substations will shrink.
The trend towards increasingly compact substations and the dynamic changes to energy infrastructures place new demands on power transformers. They are expected to provide maximum flexibility along with optimum safety and efficiency for a service life of at least 40 years.
The new Oerlikon substation is a shining example for space-saving construction. Located right in the center of a Zurich neighborhood, the system is spread across three underground levels, directly below an ewz network base. Together, the two structures take up just 30 percent of the space needed for older outdoor switching stations.
The PFISTERER Group,, has secured a leading position on the global market for high voltage insulators with the acquisition of all the shares in LAPP Insulators Holding, based in Wunsiedel, Germany from Quadriga Capital.
The mobile hybrid CrossPower energy management system is the first system that allows users to set up decentralized, robust, and scalable power grids using renewable energy anywhere in the world. The intelligent control system allows all types of available energy sources to be mixed and finds the ideal balance between energy generation and consumption.
The dry, plug-in CONNEX connection system has recently been deemed suitable for use with extra-high voltages of up to 550 kV. The universal cable system, which can withstand even the harshest weather conditions, is the only system to be certified for off-shore use.
