1.0 Capacitance and Tan d test set :

          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 Rotor Reflectometer, Type : TDR,
Make : Convex Design Ltd., Bristol, England.

               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.
