Voltage Regulated Distribution Transformer ■ SmartActiveTransformer

 Open the catalog to page 1

The economical alternative to grid expansion – optimal grid capacity utilisation: the integration of increasingly decentralised energy sources feeding renewable energy into low-voltage systems presents energy providers with increasingly greater challenges. The specified nominal voltage range of +/- 10% according to DIN 50160 only allows a maximum voltage rise of 3% for decentralised energy sources. The remaining bandwidth must be available for medium voltage, voltage drops, and setting accuracy. In this context, more and more network operators are being forced to undertake expensive...

The ideal solution for power distribution network operators Maintenance-free, long-lasting · no lifetime-limited electronics in the circuit breaker · maintenance-free for its entire lifespan thanks to vacuum technology · lifetime analogy to conventional local network transformers Low lifecycle costs · 700,000 reliable circuits make maintenance unnecessary · the on-load tap changer operates reliably throughout the entire lifetime of the transformer · motor and controller may be easily replaced as required Maximum operating reliability · critical operating conditions are excluded by the...

The SmartActiveTransformer suits any compact station The on-load tap changer was specially developed and optimally integrated with the transformer tank in which the switches operate in special vacuum cells to exclude the possibility of oil contamination, thus no second oil vessel is required for the circuit. The innovative design enables the SmartActiveTransformer to correspond with the dimensions of local network transformers, and it is easily integrated with conventional compact stations. In connection with the control cabinets, it also includes all of the functions that are required for...
