Quickly find ways to leak equipment

First, use a multimeter to measure the leakage voltage, put the multimeter switch on the AC voltage measurement file, usually placed in the AC voltage 250V position, then insert the black test pen into the soil near the device under test, and the red test pen is connected to the metal of the device. On the outer casing. At this time, look at the indicator on the multimeter. If the needle does not move, you can change the low gear in turn until the specific data is indicated as the leakage voltage of the device. If there is no indication when the test leads are at the lowest level, there is no leakage of the device.

Second, check the electric leakage with an electroscope. The inspector holds the electroscope directly to the metal casing of the electrical equipment. When the neon tube in the electroscope is illuminated, it indicates that the device has leakage and indicates that the leakage voltage is high. When the manifold is not lit, it does not indicate that the device is not leaking. It may be that the leakage voltage is low, the tube is not bright, and there may be no leakage voltage.

Third, when there is no multimeter and electroscope, you can touch the metal casing of the electrical equipment with your back. When there is a hand numb or electric shock, it means that the device has a leakage voltage. Be sure to be vigilant when there is a sense of electric shock, indicating that the leakage voltage is relatively high. It is necessary to stop the inspection to analyze the cause and use it after troubleshooting. Otherwise, an electric shock may occur.
