Verification device of NC-3 withstand voltage teste

The state promulgated the new jjg795-2004 & ldquo; Verification regulation of withstand voltage testing machine;, There are many differences from the procedures implemented in the past
In order to facilitate the measurement department to implement the new procedures
The NC-3 voltage withstand tester calibrator of flux technology (Nantong) Co
, Ltd
combines the voltage, action current and voltage withstand time of the verification test into one standard
During the verification, connect the high-voltage line of the tested voltage withstand tester to the voltage measuring terminal or current measuring terminal of the NC-3 calibrator, and then select the test item and measuring range
It can be verified without adding other instruments and wiring
It is very convenient and simple to use
Time measurement as long as the voltage withstand testing machine is started, the NC-3 calibrator can automatically start time measurement, and the time can be measured accurately in a very short time setting, such as 0
5 seconds
Compared with similar machines at home and abroad, the biggest advantage of NC-3 machine is its own load, and the resistance is designed according to 500V and 1000V
A fine-tuning resistor is set to make the action current finer and more accurate

Main technical parameters of NC-3 machine:
