Voltage breakdown tester

GB/T 18216.2-2002
6.4 It should be verified that the measured current of the subject meets the requirements of 4.4 (routine test).
Note: When superimposing an AC voltage on a DC, a device for measuring the peak current must be used
6.5 When parallel connecting a 5 pF sensor. When testing a 5 pF capacitor, the indicated value should be stable and the variation should not exceed 10%. Under these conditions
Next, the measuring device is loaded through a pure resistor (without inductance or capacitance) to generate nominal voltage and nominal current (type test).
6.6 According to 4.6, an allowable overload test should be conducted. For this purpose, a DC voltage with sequentially changed polarity and an AC voltage
Apply sequentially between the measuring terminals, during which the device is turned on and off, with a cycle of 10 seconds and a voltage value of 1.2 times the nominal output voltage
Value. After this test, the measuring equipment should be undamaged (type test).
6.7 The number of possible measurements should be determined. The number of measurements taken until the device reaches the limit of the voltage range determined by the battery
Number. During this process, the equipment should be loaded through a UN X (1000 a/v) test resistor, with each new load lasting for 5 seconds
Alternating between cycles of approximately 25 seconds (type test).
The compliance of the tests in this chapter should be recorded.
