Chauvin Arnoux CA6550 10KV/15kV High Voltage Insulation Tester
Insulation Measurement at 15kV, a job for experts
With their test voltages of up to 10 kV/15 kV, the C.A 6550 and C.A 6555 megohmmeters are expert tools for testing insulation safely and accurately. As they comply with the most recent recommended practice while taking into account future developments, they are ideal for use on rotating equipment and machinery operating at 12 kV or even higher.
The multiple test modes mean that you can both assess the insulation in qualitative terms by non-destructive testing (“I-limit” and “early-break” modes) and use samples to investigate insulation ageing problems for preventive maintenance purposes (“burning” mode). The C.A 6550 and C.A 6555 offer quick, effective checking of test execution by displaying the evolution of the test in progress in graphic form.
Thanks to their large storage capacity, complete analysis of the test sessions performed on-site can be carried out with the DataView® software after transferring the data onto a PC.

Polarization Index (PI) ratio, dielectric absorption ratio (DAR) and dielectric discharge (DD) index for testing heterogeneous multi-layered insulation
Fixed voltage mode
Step, Ramp mode:
- Results independent of temperature, detection of insulant cracking and ageing
I-limit or dI/dt (early-break) trigger modes:
- Optimization of non-destructive tests (e.g. Varistor testing)
Burning mode (no triggering)
Selectable voltage from 40 V to 10,000 / 15,300 V
Graphic LCD display of R(t) + u(t), I(t), I(u) (useful for testing semi-conductors)
