The company LST, with its comprehensive range of services, provides you with all products for the safe operation of a synchronous machine in a wide performance range.

With the founding of the company LST in the year 2000 and the long AEG history, the foundation was laid for the production of the first generation of digital excitation systems of the product line TSG2D.

Many years of experience in designing, manufacturing and commissioning of analog and digital excitation systems enabled us to launch the second generation of digital excitation systems of the IREG © product line in 2017. The new product line IREG © fulfills all IEEE requirements and technical standards.

Furthermore, we supply complex generator control cabinets including generator protection and synchronization, which are commissioned by our service staff. A focal point in our company is the modernization of existing power plants in the field of excitation systems and generator protection systems. We act independently of the generator manufacturer. The company LST is still the OEM for the analogue excitation systems of AEG worldwide. LST products are present in more than 30 countries around the world. Our team works hard to meet your requirements. Through our worldwide network, we are available in a short time.
