Hydropower project is the key in the decoration, it is related to our personal property safety, and the socket, as one of the most important link, its installation can not be ignored, generally in the socket installation, we will require to ground installation professionals, so in the later use safer, if we don't know if there is a ground wire socket, how do we judge testing?
How to judge whether the socket is grounded?
1, ready to test need test pencil, test pencil we might not use it frequently, so need to test before good, can at the same time with the hand holding the head metal part and the end of the pencil's last button, if the pencil with a little lights up, but no display on the LCD panel, indicates test pencil is good.
2, the test line, that is, the phase line, the light will be very bright, at the same time, the LCD screen also has the corresponding digital display.
3, test the zero line, then the light will be darker than the test line, and there will be no digital display on the LCD screen.
4, the last is the test ground, the effect is the same as the test zero line, if the ground is not wired in accordance with the provisions, the small light will not light.
What is the function of socket grounding?
1, to protect electrical equipment shell if through the plug connected to the ground, after the earthed socket, once produce leakage in the equipment, electrical shell with electricity, but because already connect the ground wire, can guarantee the electrical enclosure and ground potential, namely to ground voltage is zero, this ensures the contact electrical consumers won't get an electric shock, Thus, personal safety is guaranteed.
2, to prevent leakage, if the ground wire, socket hole socket with ground wire can be ground household equipment such as washing machines, refrigerators, in the event of leakage, earth and the earth are interlinked, it has to do with the resistance of the earth is less than the personal resistance, electric current can directly through the ground into the earth, thus preventing the consumer by electric shock when touching electrical appliances, guardian don't get an electric shock.
This is one small make up to introduce the methods about how to determine whether the socket grounding and role, and hope to be of help, of course test for a grounding socket belongs to a more professional problem, if consumers did not dare to try, suggest looking for professionals to test, or directly buy socket tester for testing.
