On-site service



We prefer to solve any problems on your motor or generator directly on your site, no matter whether in Europe or elsewhere in the world. It can also be taken for granted that our mobile teams use only state-of-the-art testing and measuring equipment. This enables us to perform on-site diagnoses for machines of all sizes – and then to offer you an optimum solution after evaluation. In addition to the metrological services, such as high-voltage tests, tan delta tests (power factor measurements), determination of the insulation value etc., we also offer services with our 3D-coordinate laser tracking system. With this system, we can measure machines completely.

In addition, we perform overhauls, assembly and disassembly of generators up to 250 MVA in air-cooled design for you. When performing general overhauls and repairs on your generators and motors, our engineers coordinate the service teams assigned on your premises. This includes all erection work, including provision of cranes, transport of the machines for repair at the factory, as well as subsequent reinstallation and adjustment of the overhauled system parts.
