How to analyze the high voltage transformer

In general, a transformer to convert the voltage for use in consumer electronics. Transformers "step up" high voltage or low voltage to high voltage is twisted. High Voltage Testing Set transformer is a type of transformer. As with microwave appliances, utilizing a high voltage transformer. To cause a risk of electric shock, the transformer must be removed, the capacitor before testing, they shed blood. However, the problem does not occur, a rapid, readily accessible ohmmeter, the whole procedure, it would be very beneficial. How can know the function of the transformer is useful to recognize what the results of the test mean? Do you want to resolve whether the transformer itself is bad, but it would be whether it is operating properly.

Instructions:

1. I remove the transformer from the power source.

2. In order to discharge the capacitor, you agree to the power. I think he was division, if you are using a high-voltage capacitors without exhaust resistance, the short circuit of the capacitor is indispensable. If not, it shall accept the resistor to consume power from the capacitor just their individual.

3. Make sure that the component can not be controlled by the voltage meter.

4. Cut off the high voltage from the valve guide to proper transformer. This it may be required that the set screw is detached, or may be engaged in only disconnect the line. If there is some high voltage valves, each of them we separated here.

5. I put an ohm meter to its most sensitive. For analysis of the resistance between the terminal and ground just disconnected. Indicator should be shown anywhere connected to the (50 ~ 70 O) 70 ohm resistor about stuck between two points below about 50. Considerable variance from this series shows a trans incomplete.

6. Crack a guide to the key of the terminals of the transformer of the follow-on to a similar method in the case of the high-voltage output. H V Testing Set

7. Please check the resistance meter to connect the input terminals. The meter must be presented to a very low reading down (close-up (0 O) zero ohms) between these terminals. In addition, a great deal of resistance stuck specifies the failure of the transformer between these terminals.

8. I run all tests between the input terminal and ground. Ohmmeter is supposed to be (8 O), illustrates an infinite ohms indicating that nothing to do between these points. Some finite resistance to specify the short here.

9. Disconnect the escort of productivity of low voltage, I will test the resistance value between those workstations. As with the key of the terminal, a low resistance meter, should exhibit (1 O less than) a finite rate. There is shown the difficulty of the transformer over a resistor. Insulating Oil Testers

10. Finally, I will test the position between the terminal and the low voltage production. Measuring device, you should show (8 O) does not imply a connection at all, infinite ohms. Again, any link, specify a short circuit here.

11. To clean up the workstation, then reconnect the guide, when the measured value of the resistance of the whole is displayed properly, we reconnect the transformer. In the analysis, the trouble with the system indicates that lie elsewhere.
