Products test current estimation method.
High, commercially available test currents are.
And the test current is greater than or equal to 100A.
If there is a built-in fuse,pay attention to the test current.
Short-circuit test current 1 mA nominal.
Test current ripple coefficient: less than 5%;
Diode test indication Display voltage drop:0.6 V at1.0 mA nominal test current.
No test current through the output voltage is VCC/ 2.
After filling shows"start test", the left shows the measured resistance data,the right shows the test current.
When the test current is less than 10-10A or the measured resistance exceeds 1011 ohms;
This method is very cumbersome due to the use of a large test current the DL/T475-2006 standard is recommended to be less than 50A.
The test current should not exceed the allowable current of the test device.
Each load test requires that the rotor current remains stable, andthe variation range should not exceed 1% of the test current;
In case of GST, maximum test current is 10kV/1A, and power frequency or variable frequency is 40-70Hz.
This method can obtain stable andcredible measurement results under the conditions of the test current frequency and the system power frequency.
The test current is large and fully meets the national standard requirements for testing contact resistance.
Large LCD screen, display all the data andcurves of the test voltage, test current, time and the leakage current for each item 8 items.
Because the test current for the capacitor current, the need for large-capacity test equipment.
Now DC resistance testers are all using the DC bridge method,which requires the test current to be no less than 1A, and the measurement resistance value is small.
The maximum test current is 10kV/5A when reverse wiring, power frequency or frequency conversion 40-70Hz.
In order to reduce the influence of on-site interference, there are mainly two methods currently used,one is to increase the test current, and the other is to use the different frequency method.
The waveform of test current is sine wave and the difference between frequency and power frequency is merely 5Hz.
During the test, the high-voltage side is open, the low-voltage side is pressurized, the test voltage is the rated voltage on the low-voltage side,the test voltage is low, and the test current is the rated current percentage.
External high voltage:Maximum test current 5A during positive wiring, power frequency or frequency conversion 40-70Hz.
The test current comes from a high-precision high-current constant-current power supply, which requires no manual adjustment and is quick and accurate.
A DC resistance tester can also be used for measurement, butit should be noted that the test current should not exceed 50% of the rated current of the coil, so as to avoid the increase of the DC resistance of the coil heating, which affects the accuracy of the measurement.
The test current waveform is a sine wave, and the frequency is only 5 Hz from the power frequency, and is measured using two frequencies of 45 Hz and 55 Hz;
The measured results, the study discusses the test current frequency and the influence of the arrangement of the measuring leads on the Z, R and X of the test results.
When the test current is less than 10-10A or the measurement resistance is more than 1011 ohms, the test sample, test electrode and test system shall adopt strict shielding measures to eliminate the influence of outside interference.
High input impedance:reduced test current and low power consumption, making the product body small and light, stable in performance and high in measurement accuracy.
