Generally, there are a lot of electrical appliances in our family, so there will be wires installed in the home, so there may be leakage, so we have to check the circuit when we are decorating, then we need to test Instrument, then what is the leakage switch tester ? How to use the leakage switch tester? If you want to understand the next step, let me introduce you to the small series of decoration techniques.

First, what is the leakage switch tester?

1. The leakage protector tester is mainly used to test the leakage current of the leakage protector, the leakage current and the leakage operation time. Single-phase, three-phase leakage protectors can be tested. Leakage protector action characteristics Single-chip power failure detection One of the effective means to prevent electric shock accidents in installing a leakage protector (residual current action protector) in a low-voltage power distribution system is also the latest technical measure to prevent electric fire and electrical equipment damage caused by electric leakage. The pocket type leakage protector tester mainly tests the operating current and the operating time of the leakage protector, and can test whether the leakage protector can automatically be powered off in the case of leakage.

2. It combines the advantages of domestic and foreign similar products. After careful design by our company's scientific research personnel, it is exquisite in appearance and easy to operate. It has a wide test range and provides 30 gears from 30mA to 500mA. It has perfect functions, digital display, reading retention, automatic detection, voltage reverse protection function, prompt battery replacement when battery energy is insufficient, and the tester has a low failure rate. It is an ideal product for detecting the performance of leakage protectors.

Second, how to use the leakage switch tester

1. Before the test preparation Before the tester is connected to the power supply, the “power switch” of the instrument should be in the disconnected position. The power supply should be connected to the power supply side of the leakage protector (AC220V). The phase and neutral wires cannot be connected incorrectly. The test line passes through zero. The sequence transformer is connected to the phase line of the tester power supply. The function switch of the tester is placed in the “pre-position” position. After checking the wiring is correct, turn the “current adjustment” potentiometer on the tester panel counterclockwise to zero position, and press the “power switch”. At this time, mA The table and millisecond table indications should be zero. If not, press the “Reset” button.

2. Touch the other end of the test lead bar's red plug wire to touch the corresponding fire wire (220V) of the lower pile head of the leakage protector. At this time, the normal leakage protector will trip and break, at this time the LCD screen directly above. “MANUAL xxxms is displayed (Note: MANUAL=manual, xxx is the breaking time value of the tested leakage protector). If it does not trip, the LCD will display “MANUAL fauat (fauat=failed))

3. The value of the leakage current measured with the load is not the characteristic of the leakage protector, and there is generally leakage current in the load. The magnitude of the leakage current of the three-phase leakage protector with load measurement reflects the degree of three-phase leakage imbalance in the load. The measurement method is to connect the tester power supply and test line to the power supply side of each phase at the same time, and measure it by the above two methods. Be careful, you can't use three three wiring methods, otherwise the tester will burn out .

When we are decorating the house, we will test the electric switch. What is the leakage switch tester and how it should be used? I believe that through the introduction of the above small series, everyone knows about it, then if you want to understand For more decorative information, please continue to pay attention to the decoration home Internet cafe.
