Product Description

Siemens Shunt reactors and series reactors

Shunt reactors and series reactors are used widely in A Cnetworks to limit overvoltage or shortcut current in power transmission. With agrowing number of high-voltage overhead lines in a fast-changing energyenvironment, both shunt and series reactors play a key role in stabilizingnetwork systems and in increasing grid efficiency.   Range: seriesreactors, variable and fixed shunt reactors Rated power: from 10MVAr to300MVAr Rated voltage: from 33kV to 800kV Features: compact, robust design;stable performance over service life; 3ph testing up to highest voltage andpower levels; state-of-the-art technology and design tools Optional features:low-noise/low-loss version, extended 80%-regulation range, green design options

Reactors are real all-rounders and grid trouble-shooters. Inconventional electricity transmission grids shunt reactors control voltage andcompensate reactive power, while series reactors change load flow and limitshort-circuit currents. With the increase of renewable and distributed powergeneration reactors and variable shunt reactors in particular  play asignificant role in today energy landscape with its higher fluctuation inpower feed-in. Siemens' reactors come with benefits at various levels to helpgrid operators achieve and maintain a reliable and secure power supply system:

Measuring reliability

Siemens' reactors work reliably for decades in high-voltagegrids worldwide.

The high number of units in service  more than 800 unitsmanufactured over the last decade alone  serves as proof of the validity ofour design laws. In our effort to ensure long and reliable service life, westrive for minimum tolerances in manufacturing and insist on high-qualitymaterials. Our suppliers worldwide are required to comply with the high standards, to which we hold ourselves. The result is a failure rate that is nothing short of impressive  we gladly provide you with our latest meantime between failures (MTBF) figures.

Our systematic approach to quality supports our relentlesspursuit of precision and customer satisfaction. It rests on three pillars:

Compliant with highest standards

The highest quality standards govern all processes  from reactor design to manufacturing and testing – at all our sites. Each of our manufacturing sites has been certified to ISO 9001 and holds additional local Certifications. The reactors manufactured meet all required standards, from IECto ANSI and IEEE.

Demanding supply-chain management

Siemens uses tried-and-tested technologies for windings insulation, tank, monitoring devices, connection equipment, and the tap changer, sourced from rigorously screened suppliers. The sub-supplier qualification system – independent of region or site – sets the same high quality standards, to which we hold ourselves.

Quality control, inspections and testing

Every manufacturing step is subject to quality control,rounded off by a final inspection and an acceptance test in the high-voltage test bay of the respective manufacturing site. In addition, we can conduct special tests upon request. We invite customers at regular intervals to attend tests and inspections to give them the opportunity to personally ascertain the quality of the manufactured reactor.

Siemens reactors are manufactured at state-of-the-art facilities

  • Air cushion throughout manufacturing
  • Hydraulic lifting arrangement for core assembly
  • Two fully-equipped test fields to prevent bottlenecks
  • Large capacitor bank to test shunt reactors up to 250 MVAr

Best-in-classprocesses

Constant pressure of the winding during drying processincreases short-circuit capability.

Oil impregnation after drying reduces humidity in thewindings.

Desert Climate Hall” for final assembly after dryingensures long insulation life.
