A typical application of Shunt reactors is power factor compensation of a circuit, for example to compensate for the capacitance of long overhead transmission line or for much shorter lengths of HV cable. At low loads, the remote end of these lines may rise in voltage (the so called “Ferranti Effect”). This is especially prevalent in developing countries where the system may be only lightly loaded in the early years following installation
The large coils of the shunt reactor provide inductive compensation to guard against this effect. Other advantages of shunt reactors include the prevention of generator self-excitation on leading power factor loads and the reduction of over-voltages on sound phases following a single line-to-ground fault.
Royal SMIT Transformers B.V. has an ongoing engineering evaluation process for continuous improvement and upgrade of its design programs.
Royal SMIT engineering is making full use of a high end 3D-CAD system for the complete transformer design. Active parts and tanks can be combined in one model allowing the best possible check on correct dimensioning.
Almost all engineers use 3D-CAD stations. The introduction of 3D-CAD technology was thoroughly prepared over the past years. A team of experts worked fulltime on the required tank- and active part models.
The great advantages for SMIT as well as its customers are:
Royal SMIT Transformers B.V. produces large power transformers with independent clamping of the core and windings. This clamping system is unique amongst manufacturers of large power transformers.
The independent clamping arrangement has many advantages:
Royal SMIT style windings differ from most of our competitors in having axial cooling ducts without pressboard radial spacers. This type of winding style has several advantages:
Royal SMIT Transformers B.V. has developed finite element models of the transformer tank design allowing the tank stresses and vibration levels to be accurately predicted:
Reliable Transformers with the unique single winding clamping construction are shipped wordwide to customers producing power. We have extensive experience with requirements for the nuclear industry and the renewable energy. The single winding clamping construction gives additional strength regarding short circuits and does not influence the core clamping.
Large Power Transformers have been delivered for customers choosing for Transformers with a long life span, high reliability and with the approved unique single winding clamping construction.
Reliable energy supply in all production processes is of main importance for our customers. Reliable Transformers are part of this philosophy. Our Transformers have been delivered all over the world for multiple industries chosing for quality and reliability.
Short Circuit Resistance is a major concern for customers within the railway industry. That is why our Transformers are chosen, being very reliable due to the unique single winding clamping construction and the high quality of our Transformers.
