Compared with traditional solid caps, the leakage current of EINA audio caps is merely 3uA.
The leakage current during normal operation is very small and does not affect the system operation.
All the electrical products after wet insulation decreased, the leakage current increases, even can not be used normally.
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.
If we increase the voltage, the leakage current also increases and triggers a transistor effect through layer P2.
Automatic display polarization index(PI), induced electric absorption test values than(DAR), andcan test the leakage current and capacitance.
(1) The leakage current of the zinc oxide surge arrester will increase faster with increasing voltage.
(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.
(3) The leakage current at 0.75 times UDC1mA should not exceed 50μA, or meet the specifications of the product specifications.
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.
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.
It is important to select the right residual current device for the power rating of the consumer appliances and for the leakage current.
This method makes it possible to minimize the leakage current on the body or in the ground, so it is better to use in buildings, where stringent electrical safety requirements are established.
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).
Excellent accuracy: The leakage current at HV side is meadured by digital meter accuracy: 1uA, range switch is not required, disvharge withstand current measurement function is available at low voltage side, It use precise resistor with good stability to measure high voltage.
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.
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.
Under the action of the applied voltage, the leakage current of the insulator surface also increases greatly, which obviously reduces the insulation properties of the insulating material, and even causes the insulator's dirty layer to generate heat, resulting in local arc or even full flashover.
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.
When installation cables are mechanical damaged, when laying a bridge cable directly under the plaster as well as in the presence of many circuits protected by one RCD,the sum of the leakage currents can reach again the threshold of actuating the RCD.
To this end, the constituent materials and other components of these PPE classes mustbe so chosen or designed and incorporated as to ensure that the leakage current measured through the protective integument under test conditions at voltages correlated with those likely to be encountered in situ is minimized and, at all events, below a maximum conventional permissible value which correlates with the tolerance threshold.
It operates through an electrical transformer, electromechanical relay and a mechanism for opening the contacts, which respectively detect, compare the detected(induced) current with a preliminary set limit(theso called threshold actuating the residual-current device or sensitivity), and when the leakage current is higher than the threshold actuating the RCD,the RCD is activated- it disconnects the damaged circuit.
To this end, the constituent materials and other components of these PPE classes must be so chosen or designed andincorporated as to ensure that the leakage current measured through the protective integument under test conditions at voltages correlated with those likely to be encountered in situ is minimised and, at all events, below a maximum conventional permissable value which correlates with the tolerance threshold.
After the dirt absorbs moisture, the conductivity is improved, which not only causes surface flashover, butalso may increase the leakage current, causing the insulation sleeve to heat up and cause porcelain damage or even breakdown.
To this end, the constituent materials and other components of those types of PPE must be chosen or designed andincorporated so as to ensure that the leakage current measured through the protective integument under test conditions at voltages correlated with those likely to be encountered in situ is minimised and, in any event, below a maximum conventional permissible value which correlates with the tolerance threshold.
Serve to monitor the dangerous value of the leakage ground current that can cause e.g.
Relatively high and fluctuating leakage current.
