When voltage is applied to the input winding, it is transmitted to the output windings. This state of affairs indicates that the transformer is working properly. In this experiment, you need to be extremely careful. The fact is that 2 kV is life-threatening. 4 Volts are quite suitable for measurements in a heated state.
The transformation ratio value can show problems with the transformer. At 220 V, the high-voltage winding will give 2000 at the output. If all windings are disconnected from the power supply, the action will be carried out at idle. Supplying power to the high-voltage output will result in the primary winding of the transformer being in good condition being 24.2 Volts.
The transformer should be replaced with a new one or repaired lebanon telegram data if the windings are broken, or if there is an interturn or interphase short circuit.Here it is necessary to perform the appropriate calculation.
You can find it on the side where the transformer is located. It is in a durable casing with dielectric characteristics. It is necessary to remove it and ring it with a multimeter. This can be done in one of two modes: ringing or measuring resistance. The burnt-out module is replaced by melting and inserting a corresponding nominal value.
Voltage multiplier capacitor
Before starting work, it is necessary to remove the charge that is present on the plates. If you do not do this, you can get burned by electricity. Capacitor capacity is easily and simply measured with the same multimeter. The readings must fully correspond to the factory ones. You can also take into account the design features of the parts in advance. The accuracy of the readings is affected by the contents of the microwave oven case. For example, it may also contain a resistor with current-limiting properties.
Testing a high voltage diode
A multimeter cannot help in this case, since it consists of compound diodes located in a series chain. The voltage drop on them is too large and cannot be compared with the reference signal.
