The leakage current is less than 100 Nano Amps.
High pressure when measuring the leakage current< 10 uA.
The leakage current clamp supplies 3 stored limiting values.
During the test, 6 milliamp meters show the leakage current of each corresponding test object.
The leakage current is measured and computed to get the insulation resistance.
This solution has made it possible to keep the common-mode voltage constant and reduce the leakage current to zero.
Error rang of the leakage current test< 1%±1word.
At present, only insulated boots, insulated gloves, and bucket-arm vehicles are required to measure the leakage current.
Pieces of insulated boots or insulated gloves for testing at the same time, respectively,to measure the leakage current.
(1) The leakage current of the zinc oxide surge arrester will increase faster with increasing voltage.
EN/EC61800-5-1(Power Drive System Product standard) requires special care if the leakage current exceeds 3.5 mA.
If the leakage current and voltage are greater than or less than the standard value, it should be repaired.
Automatic display polarization index(PI), induced electric absorption test values than(DAR), andcan test the leakage current and capacitance.
AC hipot test is done by applying a high AC voltage on the test conductor and measuring the leakage current.
Insulated boots insulated gloves are not allowed to break down during the withstand voltage test and the leakage current must not exceed the required value.
(3) The leakage current at 0.75 times UDC1mA should not exceed 50μA, or meet the specifications of the product specifications.
(4) Press the 0.75UDC1mA button again, the voltage drops to 0.75 times,record the leakage current when the microampere meter reading is 0.75UDC1mA.
Switch on and raise the voltage, then maintain the voltage at the target voltage and take timing, reduce the voltage in time and switch off, save anddisplay the report of the leakage current for each item.
When the instrument measures the voltage U1mA at 1mA, the leakage current value at 0.75U1mA can be obtained at the same time, and the operation is very simple.
Large LCD screen, display all the data and curves of the test voltage, test current, time and the leakage current for each item(8 items).
If the leakage current reaches 10mA, it is regarded as a breakdown, the corresponding overcurrent protection action, and the corresponding"withstand voltage indicator" goes out, indicating that The test object failed.
If the core wire is positive, the moisture penetrates into the lead package,the moisture in the insulation decreases, the leakage current decreases, and defects are not easily found.
It can reflect the actual value of the leakage current of the measured body through the leakage current display and compare the pressure resistance between different batches of different products or different manufacturers to ensure the safety of your product.
At present, the external protective layer mostlyuses HDPE sheath material, passed the DC 25kV/5min withstand voltage testbefore out of factory, the leakage current is less thandozens of µA.
When the time is up, the voltage shall be decreased to zero and the power shall be switched off, in the meantime the leakage current of each tested piece shall be displayed and the testing result shall be saved automatically.
If the core is connected to the negative polarity, The water will concentrate on the core wire,the moisture in the insulation increases, the leakage current increases, and defects are easily found.
