Transformers generally convert voltage for use with appliances. The high-voltage “step up” transformers turn lower voltages in higher voltages. A high-voltage transformer is a type electrical transformer. A high voltage transformer is used in appliances like microwaves. To avoid shock risk, high-voltage transformers must be dismantled and capacitors must be bled before they can be tested. The entire process becomes very easy, fast and informative when a resistance tester is readily accessible. Knowing the workings of the transformer is key to understanding the meaning of the test results. It will tell you if the transformer has a problem or is functioning correctly. 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. The transformer must be removed from the power supply.
2. Consent to power exhaust from capacitors. If the division uses high-voltage capacitors without exhaust resistors it may be necessary to short circuit the capacitors. If this is the case, it may be necessary to short-circuit the capacitors.
3. Verify that there is no control on the component with the Voltmeter.
4. Take the high-voltage Transformer Guide off its valve. This may be unplugging of the wire. If you have multiple high-voltage vales, it is best to separate them all.
5. Place the Ohmmeter where it is most responsive. Analyze resistance between terminals that have been detached and the ground. The indicator should be able to connect between fifty and seventy Ohms (50–70 O) of resistance. The indicator should show considerable variance between these points to indicate an imperfect transformer.
6. Divide the guide along the key in terminals of the transformer. Next, use the same method as for the high voltage outputs.
7. You should check the ohmmeter at each input terminal. This meter should give a very low reading, close to zero ohms (0O),) between the terminals. Resistance between these terminals is an indication of a transformer fault.
8. Check between all the input terminals. The ohmmeter can be used to indicate infinite ohms (8 O), but there is no relationship between them. Here, a short circuit is designated by some finite resistance.
9. You can remove the low voltage productivity escorts and test for resistance at those workstations. As with key in terminals the ohmmeter will show a low and finite evaluation (less of one O). An excess resistance indicates that the transformer is not working properly.
10. Finally, test between the low voltage productivity terminals of the measuring device and the position. A measuring device should not show any connection. This link signifies a circuit.
11. If the resistance readings are all correct, please clean out the workstations. Connect the guide to the transformer, and then connect the transformer. The analysis indicates that the problem lies elsewhere.
