Chauvin Arnoux CA6547 5kV HV Insulation Tester

Chauvin Arnoux CA6547 HV Insulation Tester

The Chauvin Arnoux CA6547 HV Insulation Tester is a high voltage megohmmeter that can also measure voltage up to 5100V, capacitance up to 49.99F and leakage current up to 3000A. Insulation resistance can be measured from 10kΩ to 10TΩ thanks to a test voltage which can be fully adjusted between 40V and 5100V or pre-set at 500V, 1000V, 2500V or 5000V.

Several advanced features on the Chauvin Arnoux CA6547 offer enhanced measurement analysis as well as a simplified ‘Go/No go’ indication of insulation quality. Polarisation index and dielectric absorption ratio give insulation quality assessment that makes adjustments for temperature and humidity whilst dielectric discharge index reveals impurities and faults in heterogenous or multi-layered insulation.

Programmable alarms for high or low resistance can be set by the user and a smoothing function helps produce a stable reading when fluctuations are present. The test duration can be programmed by the user to make sure that transient currents do not interfere with results. An R(t) graph can be plotted using the samples provided by the CA6547 during a programmed-duration test.

The smart capabilities of the Chauvin Arnoux CA6547 allow the user to keep hold of results on the instrument itself as well as transferring them to a computer via an RS232 communication cable. Optional DataView software allows the user to recover readings, map trends and create reports whilst hard copies of results can be produced through an optional parallel printer.

Practical features including a wide range of accessories make the Chauvin Arnoux CA6547 very easy to use. The LCD screen shows results clearly and simply and operation is carried out through a clearly-labelled dial and buttons. It is light and easy to manoeuvre on site and has protective, IP53-rated casing to withstand the rigours of regular use.
