The operation of the condition monitoring testing instrument is fully controlled by PC (Laptop) and supervised by sophisticated software. This software controls the complete test procedure, collects the test data, analyses the data, display the same in tabular and graphical format. The test data for respective equipments are stored for establishing the trending periodically, which is very important for any condition monitoring testing. |

6.0 RSO Test Set : For Rotor Earth fault and Rotor Winding Inter turn fault detection. The testing instruments used are,
Rotor Reflectometer, Type :
TDR, |
|
This is a world
renowned, highly accurate Rotor Reflectometer for Recurrent Surge
Oscillograph test. There are several modes in which the Reflectometer can be used. These are, a) Testing of stationary rotor within generator. b) Testing of rotor at speed within generator (unexcited) c) Testing of rotor when removed from generator Testing set can be used for, a) Fault between winding and rotor body (earth fault). b) Inter turn fault. c) High resistance joint in rotor. d) Inter winding fault. |
