Chauvin Arnoux CA 6545

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. POLARISATION INDEX (PI) & DIELECTRIC ABSORPTION RATIO (DAR): 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. DIELECTRIC DISCHARGE INDEX (DD): This test measures the dielectric absorption of a heterogeneous or multi-layer insulant and will reveal the presence of impurities or a faulty layer. TEST WITH PROGRAMMABLE DURATION To deal with the whole range of measurement situations (electrical equipment, telecom installations, etc.) and measure as accurately as possible, the CA6545 offers the possibility of selecting the test voltage by means of the Var 50-5,000 V setting on the rotary switch. The voltage can be adjusted between 40 V and 1,000 V in 10 V increments and between 1,000 V and 5,100 V in 100 V increments. FEATURES Digital filtering of insulation measurements. Automatic voltage measurement. Automatic detection of the presence of AC or DC external voltage on terminals. Threshold programming, to trigger alarms using audible beeps. Timer for measurement time checks. Protection of the device by fuse, with detection of defective fuses. Automatic discharge of the residual high voltage on the equipment tested. Automatic power save mode of the device to save battery power. Indication of battery charge condition. Large backlit LCD screen with a wide range of indicators.
