NRZK-2000 series vacuum interrupter tester is used to calibrate the vacuum degree of the vacuum interrupter with single-chip computer as the main control unit the testing process is fully automated. The sampling design of the instrument uses the ion charge to do the calibration instead of using the current peak value to do the calibration in the past. Thus effectively inhibited the disturbances of transient power during the test so the test is stable and reliable. Because the instrument adopts computer as the main control unit the instrument can conveniently deduct the leakage current caused by the environmental factors.
NRZK-2000B vacuum interrupter tester is an upgrading and improved products after the several field test. The product has the advantages of compact structure light weight shorter testing time higher measuring reliability and stability higher accuracy and more perfect function.
