In its site-proof case, the Chauvin CA6547 megohmmeter can be used for quantitative and qualitative analysis of insulation. It also automatically measures voltage, capacitance and residual current.
In addition, this model offers memorisation of measurements and an RS232 link for controlling the instrument and processing the data using computer software.
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.
Measurement range: 10 kΩ to 10 TΩ.
4 fixed test voltages.
Adjustable test voltage position: 40 to 5,100 V in 10 V or 100 V increments.
Large backlit LCD screen with digital display and bargraph.
Quantitative insulation analysis: DAR, PI and DD (dielectric discharge) quality ratios calculated automatically and R(t) stored.
Large number of functions: programmable test duration, test voltage locking, smooth function, programmable alarms, etc.
Power supply: NiMH rechargeable battery for 30 days' operation with 10 DAR measurements and 5 PI measurements per day.
