Haefely VTM15000
The VTM15000 is used for insulation testing with 1.2/50us voltage impulses.
The VTM15000 runs together with a Haefely combination wave generator such as PIM100 or PSURGE4010. The output voltage of the generator is doubled, the voltage wave shape remains the same. The current wave shape is not defined any more.
For insulation testing a VTM15000 and a combination wave generator can be used. The lightning impulse is the most common impulse shape for testing insulations. No flash over should occur during testing.
Designed to meet and exceed the requirements of:
- IEC 60060-1
- IEC 60335-1
- IEC 61010-1
- IEC 61180-1
- IEC 61009-1 and 61009-1
Applications:
- Insulations
- Creepage distances
- Clearances
- Many IEC, ANSI, UL & EN Product standards
- Other international requirements for voltage impulses
