Product Details

Chauvin Arnoux CA6555 HV Insulation Tester

The Chauvin Arnoux CA6555 HV Insulation Tester has an adjustable test voltage from 40V up to 15kV as well as pre-set test voltages of 500V, 1000V, 2500V, 5000V, 10,000V and 15,000V. This allows resistance measurement up to 30TΩ whilst specialist tests like step and ramp voltage highlight falls in insulation resistance at higher voltages. Stop-voltage modes (i-limit, early break) allow non-destructive testing but a burning mode is also available for complete testing on samples. Additional measurement functions include capacitance (49.99µF), voltage (4000V) and leakage current (8mA). These capabilities make it suitable across manufacturing industries and in electricity distribution.

To accurately assess intrinsic insulation quality (unaffected by temperature and humidity), the Chauvin Arnoux CA6555 calculates polarisation index (PI) and dielectric absorption ratio (DAR) whilst programmable-duration tests can be set to negate the effects of stray transient current. For multi-layer or composite insulation, dielectric discharge index (DD) helps detect faulty layers or deterioration. Relative mode compares ppm/V ratios and real-time graphs can be plotted including R(t)+u(t), i(t) or i(u).

A simple ‘Go/No go’ indication can be shown on the Chauvin Arnoux CA6555’s graphical LCD display for when quick results are needed. Furthermore, a filter mode smooths unstable readings and a reference temperature can be calculated to provide consistency in insulation testing. The Chauvin Arnoux CA6555 has a large internal memory with space for up to 80,000 readings and these can be transferred to a PC via the USB cable provided. Supplied DataView software facilitates data transfer and also allows trend mapping, reporting and analysis on the user’s PC. Time stamps can be saved alongside files thanks to the clock.

The Chauvin Arnoux CA6555 comes with a full set of accessories and a 12-month warranty. It is safety rated as Cat IV 1000V and is very easy to transport, weighing just 6kg with an ergonomic ‘suitcase’ design.
