  • Description

    Chauvin Arnoux CA6550 10kV HV Insulation Tester

    The Chauvin Arnoux CA6550 HV Insulation Tester is a powerful megohmmeter with a maximum test voltage of 10kV and an insulation resistance range of 10kΩ to 25TΩ. Fixed voltages are available from a minimum of 500V but a specific voltage between 40V and 10kV can be programmed according to the user’s needs. Voltage, capacitance and leakage current measurement add more depth to insulation inspection whilst voltage ramp and voltage step insulation testing (burning, early break, i-limits modes) help reveal drops in resistance at increased voltages. These capabilities make the instrument suitable for a range of sectors including electricity transmission and distribution.

    Several advanced features on the Chauvin Arnoux CA6550 make insulation analysis even more detailed. Polarisation index (PI) and dielectric absorption ratio (DAR) calculation negate reading variations related to temperature and humidity whilst programmable-duration testing prevents corrupt results due to transient current. Dielectric discharge calculation permits fault-finding on heterogenous insulation and relative mode can compare ppm/V ratios. Several graphs can be plotted using readings from the tester including R(t)+u(t), i(t) or i(u).

    Aside from complex analysis, the Chauvin Arnoux CA6550 also offers a ‘Go/No go’ indication of insulation condition via its graphic LCD display. A filter mode helps smooth fluctuating readings and a reference temperature allows the tester to calculate resistance at the specific temperature. Excessive damage to insulation can be avoided by setting the tester to stop testing once a fault is detected whilst a burning mode allows destructive testing on samples.

    The Chauvin Arnoux CA6550’s large internal memory has space for up to 80,000 readings and these can be transferred to a PC via the supplied USB lead. DataView software is provided as standard to enable data transfer and analysis as well as reporting and trend mapping. Time stamps can be saved with files thanks to a real-time clock.

    A full set of accessories mean that the Chauvin Arnoux CA6550 is ready to use straight out of the box and it has a 12-month manufacturer’s warranty. A Cat IV 1000V rating certifies that is very safe to use whilst the light weight of just 6kg makes it easy to transport.
