VSS 500N12 – 12kV Voltage surge simulator

The VSS 500N12 is a surge voltage simulator specifically designed to test insulation material, components, sockets, connectors, cables and many more items to their voltage withstand capability. Testing the voltage withstand capability by means of a transient test pulse is the most common alternative to tests using a.c. or d.c. voltages.
By means of the built-in voltage and current monitors and the Spark Over Detection you are offered detailed test results to judge the quality of the DUT.
Safety precautions are taken to assure safe operation at this high voltage level. The VSS 500N12 provides interlock and warning lamp control. By means of an optional test box the operator can be further protected to avoid direct contact with high voltage and to avoid harm from exploding components or fragments of them when failing.
iec.control remote control and documentation software allows fully automated testing.

ITU-T impulse test generators

The circuit in the figure below using component values in reference of Table K1 of the normative Annex K of the  IEC 60065 standard

The circuit reference 2 of Table K.1 generates 1,2/50 us impulses (1,2 us virtual front time, 50 us virtual time to half value) as specified in IEC 60950-1 and ITU-T Recommendation K.44 to simulate transients in power distribution systems.
The impulse wave shapes are under open-circuit conditions and can be different under load conditions.


Easy to operate

Front panel menu and function keys enable the user to program his test routines quickly and accurately. The cursor allows fast control of all test parameters of the programmed routine, thus test procedures are simplified and confidence is generated that every step is carried out correctly.
