Drive systems - engineered by HELMKEHELMKE is a worldwide acknowledged competence for the delivery of complete drive systems. The converter cabinets engineered by HELMKE are projected and manufactured for customized and branch-specific applications.
6 MW HELMKE FULL LOAD TEST FIELDTo meet customers requirements and HELMKE's aspiration to work always with state of the art technologies, the HELMKE Group has invested in a new testing field on its location in Pulversheim, France. The testing field is also available for final customer inspections and external testing orders.
During normal operation electrical components and mechanical bearing parts are warming up but are protected against overheating by constructive measures. In case of failure typical local hotspots occur which may lead to consequential damages but these can simply be identified by thermal analysis.
The thermal surface conditon can be measured by using non-contact infrared technology. Thermography is an imaging method which measures the surface temperature of complete units showing a coloured image. Hotspots can be identified quickly and easily. These measurements do not affect the operation and it is not necessary to switch off the electric supply.
Comprehensive knowledge regarding the fuction and general thermal aspects of the object are required in order to evaluate the thermographic pictures and to distinguish correctly between failure hotspots and warming during operation and to analyse trends.
By own construction of electrical machines and components, examinations during production and repair as well as service at site our specialists have this experience. Short- and medium-term recommendations for action prevent a breakdown or damage especially of the equipment in operation.
Special constructions support this maintenance and analysis method already when designing the machine by providing access possiblities to the area to be monitored and by installing infrared-transparent inspection windows.
