Stator inductance test
This test is suitable to detect internal stator coil short-circuits.
Depending on the location of a possible short-circuit (number of shorted wires), the resistance of the coil still
shows a value within tolerance but the inductivity is out of tolerance. This leads to an increased stator current
and can destroy the rotor control unit.

- Stator links not removed.
- Stator wires U-V-W disconnected.
This check can be performed with a low-cost inductance
measuring device obtainable locally or can be ordered at the
SLI Hamburg with the 12NC 4512 101 77141.
Please send the measuring results referring to the tube type and serial number together with generator serial
number and customer/site data to:
