Generally, Transformers turn voltage for make use of in appliances. High-voltage or "step-up" transformers twist lower voltages into higher voltages. A high voltage transformer is a type of electrical transformer. An appliance similar to microwaves utilizes high-voltage transformers. As they cause a risk of shock, the transformer must be detached, and the capacitors bled, prior to testing. With a willingly accessible resistance tester, however, the entire policy becomes trouble-free, fast and extremely informative. Knowing how the transformer functions helps recognize what the outcome of the tests mean. It will decree whether the transformer itself is faulty, or if it is operating appropriately.
Instructions:
High Voltage Power Supply 10 Kv
1. Separate the transformer from its power supply.
2. Consent to power to exhaust from the capacitors. If the department utilizes high-voltage capacitors without exhaust resistors, it may be requisite to short-circuit the capacitors. If not, just agree to the resistors to consume power from the capacitors on their individual.
3. Check that the component has no control with the voltmeter.
4. Cut off the high-voltage transformer guide from its valve on the transformer suitable. This may engage just unplugging the wire, or it may need that a set screw be detached. If there are any high-voltage valves, Separate each of them now.
5. Place the ohmmeter to its most responsive. Pathology for resistance among the terminal just detached and the earth. The indicator should exhibit anywhere connecting about fifty to about seventy ohms (50-70 O) of resistance stuck in the middle of these two points. requisite variance from this series indicates an imperfect transformer.
6. Divide the guide to the key in terminals on the transformer, subsequent to the similar method as for the high-voltage outputs.
7. Check with the ohmmeter connecting each input terminal. The meter should gift a very low down reading (close up to zero ohms (0 O)) among these terminals. Also a great deal resistance stuck in the middle of these terminals specifies a fault in the transformer.
8. Test in the middle of all of the input terminals and the ground. The ohmmeter be supposed to expound infinite ohms (8 O), representing no association at all in the middle of these points. Some finite resistance here designates a short circuit.
9. Separate the low-voltage productivity escorts, and test for resistance in the middle of those workstations. The ohmmeter should show a low, finite estimate (less than one O), as with the key in terminals. In excess of resistance there shows a mystery with the transformer.
10. At last, test in the middle of the low-voltage productivity terminals and the position. The measuring gadget should demonstrate infinite ohms (8 O), signifying no association at all. Once again, any link here specifies a short circuit.
11. If the entire resistance readings appear proper, clean off the workstations and reconnect the guide, then reconnect the transformer. The Pathology indicates that any troubles with the system lie down elsewhere.
