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.
Scope of order:
Acceptance test at a system consisting of: Medium voltage frequency converter and asynchronous motor with no-load and load test as well as extensive function tests at the frequency converter.
|Frequency converter||- 2,500 kVA; 6000 V; 50 Hz|
|Motor||- 1,560 kW; frame size 500; 04-pole; 6,000 V; 50 Hz|
- Speed range 0 - 1,500 min-1 (M ~ n2),
- Explosion protection Ex nA IIC T3 Gc
Scope of order:
Acceptance test at a converter-fed high voltage machine with direct oil cooling. Performance of an extensive no-load and load test at different speeds.
The directly oil-cooled machine requires the installation of an oil re-cooling system.
