5. Creating & Conducting Test on a New Job
Before Starting a Test on the Test Bench the User has to create a new Job
Rating of the Transformer
Design Losses
Tap Details
Impedance & other Details
To Start a Test select a Job from the main screen
From the Test Selection Menu select on the Test to be conducted on the Transformer

6. Creating a New Job

7. Selecting a Job for Conducting Tests

8. Test Selection Menu

9. Load Loss Measurement Test
The Test Bench determines the CT & PT to be used based on the Job ratings and Select the same automatically
It also selects the TAP of the Intermediate Transformer automatically
Based on the ratings of the Job the Test Bench automatically calculates and adds the required Capacitors
The Test Bench Conducts the test automatically, records the reading and Stops the Test
In case of abnormality in the results the Test is stopped Immediately

10. Load Loss Measurement Test

11. No Load Loss Measurement Test
The Test Bench determines the CT & PT to be used based on the Job ratings and Select the same automatically
It also selects the TAP of the Intermediate Transformer automatically
The Test Bench Conducts the test automatically, records the reading at three different percentage of LV/HV Voltage and Stops the Test
In case of abnormality in the results the Test is stopped Immediately
In case the Test is conducted in manual mode Capture Buttons are provided to capture the Test results from the Power analyzer

12. No Load Loss Measurement Test

13. Induced Over Voltage Test
The Test Bench determines the Voltage to be applied to the Job based on its ratings
The Test Bench automatically starts the Generator and builds up the voltage to the desired level
On reaching the desired level the Test is conducted for a time period of 60 Seconds
On completion of 60 seconds the test results are recorded automatically and the System is shut down
In case of abnormality in the results the Test is stopped Immediately

14. Induced Over Voltage Test

15. Separate Source Voltage Test
The Test Bench determines the Voltage (KV) to be applied to the Job based on its ratings
The Test Bench automatically slowly builds up the voltage to the desired level in the HV Shooter
On reaching the desired Voltage the Test is conducted for a time period of 60 Seconds
On completion of 60 seconds the test results are recorded automatically and the System is shut down
During the entire Test Period the System monitors the Leakage Current and Trips the System in case of a Job Failure
In case of abnormality in the results the Test is stopped Immediately
