Chauvin Arnoux CA6547 5kV Digital Insulation Tester (Megohmmeter)

Overview
The Chauvin Arnoux CA6547 is a high-precision, 5 kV digital insulation tester (megohmmeter) designed for both quantitative and qualitative insulation analysis in industrial, utility, and maintenance settings. Built with ruggedness in mind, the instrument is housed in a site-proof case suitable for severe field conditions. It supports fixed and programmable test voltages, advanced diagnostic ratios (DAR, PI, DD), large memory, and multiple communication options. The CA6547 is ideal for measuring insulation integrity in cables, transformers, motors, generators, and other high-voltage equipment.

Key Features

• Insulation resistance range from 10 kΩ to 10 TΩ for high sensitivity to detect insulation degradation.

• Fixed test voltages at 500 V, 1,000 V, 2,500 V, 5,000 V; adjustable voltage from 40 V to 5,100 V in 10 V or 100 V steps.

• Automatic calculation of DAR (Dielectric Absorption Ratio), PI (Polarization Index), DD (Dielectric Discharge) ratios.

• Plotting or recording of R(t) curves to monitor insulation over time under test.

• Large backlit LCD display with numeric and bar-graph elements for clear, real-time feedback.

• Programmable test duration and alarms; ability to lock test voltage; smooth display to improve reading stability.

• Memory capacity large enough to store several thousand measurements; USB / RS-232 enabled for exporting data or controlling via PC.

• Rechargeable NiMH battery, with up to ~30 days of typical usage (10 DAR tests + 5 PI tests per day).

• Complies with safety standards: IEC 61010-1 (Cat. III 1000 V / Cat. I 2500 V) and IEC 61557.

Applications
The CA6547 is suited to a variety of applications, including but not limited to:

• Electrical preventive maintenance for industrial plants, power stations, and substations.

• Inspection and testing of transformer windings, motor stators, cable insulation, generator insulation.

• R&D and quality control in insulation materials, coatings, varnishes.

• Commissioning and condition monitoring in high-voltage installations.

• Use in utility companies, maintenance contractors, service centers, and OEMs needing reliable insulation diagnostics.
