How to analyze a high voltage transformer

Transformers transform voltage to be used in appliances. The “step-up” or high-voltage transformers transform lower voltages to higher voltages. A high voltage transformer can be described as an electrical transformer. A high-voltage transformer is used to power appliances that are similar to microwaves. The high-voltage transformers can be dangerous and should be removed. The whole process can be made easy and fast by using a readily available resistance tester. Understanding the function of the transformer will help you interpret the results. It will determine whether the transformer is defective or operating properly. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.


1. Take the transformer out of its power supply.

2. Power to exhaust the capacitors requires consent. Short-circuiting capacitors may be required if high-voltage capacitors are used in a division that does not have exhaust resistors. If the answer is no, the resistors can be used to take power from the capacitors.

3. Make sure the component is not controlled by the voltmeter.

4. You can remove the high-voltage transformer valve from the transformer. This can be done by unplugging the wire or it might require that a set screws be removed. You should separate any high-voltage devices that are connected together.

5. Place the ohmmeter at its most responsive. Analyze the resistance between the terminal detached and the Earth. The indicator should have a resistance between 50 and 70 ohms (50 to 70 O) everywhere. This series may show significant variation.

6. Divide the guide between the key-in terminals of transformers, and then follow the same process as for high voltage outputs.

7. Each input terminal must be checked with the ohmmeter. You should see a low reading on the meter (close to zero (0 O) between these terminals). If there is a lot resistance between the terminals, it could indicate a fault with the transformer.

8. The ground and all input terminals should be tested. The ohmmeter should display infinite ohms (8 O), indicating no relationship between these points. This is a short circuit.

9. Take out the low-voltage productivity cords and check for resistance between workstations. As with the key for terminals, an ohmmeter should give a finite evaluation of less than one O. If the resistance is too high, it indicates a problem with your transformer.

10. Last, you need to test the position and the low-voltage productivity termins. The measuring device should show infinite ohms (8 O), meaning there is no connection. Again, any link indicates a short circuit.

11. If all resistance readings seem to be correct, wipe off the workstations. Then reconnect the guide. Any problems found in the system are elsewhere, according to the analysis.
