Haefely Test AG products

The new AXOS 5 - Compact integrates all of the best features of our stand alone test systems into one single economic solution. It is capable of 5kV EFT/Burst, 5kV Combination Wave (1.2/50us & 8/20us), AC/DC Dips & Interrupts(*) and Pulsed Magnetic Field(**). The unit also includes an integrated single-phase coupling decoupling network (CDN) for EMC testing applications up to 16A.The expandable functionality allows for quick and completely automated testing to the most common IEC, EN, ANSI, IEEE and UL standards. The AXOS unit can either be operated via front panel by large color graphic interface or remotely from the PC. The easy to use menu together with the availability of predefined test routines for different standards makes testing easy and reliable, even for less frequently users.

The KAL 9510 has been designed to fulfill the standard requirements of a PD calibrator. Its wide range (from 1 pace to 50 no), its small injection capacitor, carefully selected features and intuitive user interface makes the KAL 9510 unique.

The 4761 high precision standard current comparators is used as comparison standard in the differential method (bridge) measurement of current instrument transformers together with the measuring instruments type 2763 and 2767. The special active flux compensated design of these comparators results in negligible current errors.These units can also be used as current measuring range extension for C and tand measuring equipment.
