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 («burn-in» 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.
