Power Measurement using dynamometer
Procedure
Configuration:-
- Select motor size , diameter of drum and check/click the configuration button. (we are considering standard single phase motor sizes)
- Click on Check Configuration
Basic Knowledge -
- Answer all the questions and click on next level
Simulation-
Part A
- Click on motor and start cold water supply
- Click on Engine image and start loading the weight
- Check the spring balance reading and click on Submit button beside meter reading
- Calculate the power and submit the answer to left side text box
- Repeat the process for 5-6 times with different loads and observe the table reading and change in power with weight
Part B
- Start the cold water pump for cooling system
- Start the induction motor with no load condition and check the power sensor reading
- calculate the standard power (upto two decimals) for no load condition and submit the answer
- load the weight , start induction motor and check the sensor power reading (torque sensor reset to zero and engine stops)
- calculate the standard power (upto two decimals) for load condition and submit the answer
- Repeat the same process for from point no. 3, loading the till the maximum weights
- Observe the reading , calculate the standard torque for every observation and submit the answer
- plot the graph by clicking on "show graph" button after taking atleast 5-6 readings
Fault Finding:
- Observe the shown table and select the fault accordingly
- After selecting the correct fault. All stages are completed
