In a site-proof case, the Chauvin Arnoux C.A6545 megohmmeter makes a quantitative and qualitative analysis of insulation. It also automatically measures voltage, capacity and residual current. The multiple functions not only qualify the measured insulation, but also provide real preventative maintenance.


Insulation is sensitive to temperature and humidity variations. In addition, measurement is affected by the appearance of disturbance currents. To overcome these effects, long-term measurements must be performed and the PI and DAR coefficients must be calculated. They will then allow qualification of the insulants and their ageing.


This test measures the dielectric absorption of a heterogeneous or multi-layer insulant and will reveal the presence of impurities or a faulty layer.
