Methods of Testing on Machine
Q. Explain the methods of testing
(1) Direct Testing of Machine
(2) Indirect Testing of Machine
(i) Direct method of testing : In this method the machine is directly connected with the load or a pulley and brake arrangement is provided or a electrical load may be connected in the form of a calibrated machine Brake test and calibrated machine test are the examples of direct tests.
(ii) Indirect method of testing : As the name suggests load is not connected directly on the machine but it is run on no load and the data obtained from the no load test is used to find the efficiency, losses ctc at different loads. Swinburne’s test is the example of indirect test.
