Chauvin Arnoux CA6549 5kV HV Insulation Tester

Chauvin Arnoux CA6549 HV Insulation Tester

The Chauvin Arnoux CA6549 HV Insulation Tester is a highly sophisticated megohmmeter with several advanced features in addition to insulation resistance measurement between 10kΩ and 10TΩ. Pre-set test voltages of 500V, 1000V, 2500V and 5000V are available whilst it is also possible to manually set the voltage between 40V and 5100V. Other measurements include capacitance (49.99F), voltage (5100V), and leakage current (3000A). Step voltage mode allows quantitive assessment of faulty insulation through a rising test voltage.

Several additional options allow the user to make the most out of the Chauvin Arnoux CA6549’s expansive measurement capabilities. Adjustable alarms can be set by the user and the readout has a smoothing function for producing stable readings from fluctuating outputs. To help ensure accuracy, tests can be carried out with a programmable duration which negates problems related to stray transient current.

Results are aided by polarisation index and dielectric absorption ratio which give a true picture of insulation quality whilst dielectric discharge measurement can detect faults in multi-layer or composite insulation. Aside from advanced, qualitative readings, a simple ‘Go/No go’ indication is also available.

A major feature of the Chauvin Arnoux CA6549 is its large, graphic display. This can project a real-time R(t) graph on screen as well as providing clear, concise analytics across a wide range of different assessment criteria. A reference temperature can be set at the push of a button and internal memory allows storage of several thousand results.

Readings can be transferred to a computer using the included RS-232 cable. From there, Chauvin Arnoux DataView software serves to map trends, print test protocols and create spreadsheet reports. Printing via a parallel or series printer is possible for instant hard copies whilst the hard casing and ergonomic, lightweight design make the Chauvin Arnoux CA6549 perfect for use on site. It has an IP53 ingression rating and is safety-rated as Cat III 1000V.
