Description

Chauvin Arnoux CA6545 5KV Megohmmeter

Performance in the field

In their site-proof casing suitable for the severest measurement conditions, the CA6505, CA6545, CA6547, and CA6549 megohmmeters offer you the best in insulation testing in terms of accuracy and expertise. As soon as they are connected, they measure voltages, frequencies, capacitances, and residual currents on the installation or equipment to be tested. With their multiple functions, they not only qualify the insulation measured but also ensure genuine preventive maintenance.

CA6545 Megohmmeter Comes Supplied With:

  • Carrying bag containing: 
    • 2 safety leads 3 m long with HV plug and HV crocodile clip (red/blue) 
    • 1 guarded safety plug 3 m long with an HV plug with rear connection and an HV crocodile clip (black) 
    • 1 lead with rear connection (blue) 0.35 m long
    • 1 main power cable 2 m long
    • 1 simplified operating manual
    • 1 operating manual in 5 languages

Key Features:

  • measurement range: 10 kΩ to 10 TΩ

  • 4 fixed test voltages: 500 / 1,000 / 2,500 and 5,000 V

  • adjustable test voltage position: 40 to 5,100 V in 10 V or 100 V increments

  • large backlit LCD screen with digital display and bar graph

  • quantitative insulation analysis: DAR, PI, and DD (dielectric discharge) quality ratios calculated automatically, and R(t) stored

  • large number of functions: programmable test duration, test voltage locking, smooth function, programmable alarms, etc.

  • power supply: NiMH rechargeable battery for 30 days' operation with 10 DAR measurements and 5 PI measurements per day

  • electrical safety: IEC 61010-1 Cat.III 1000V or Cat. I 2500V and IEC 61557

  • dimensions: 270 x 250 x 180 mm; weight: 4.3 kg

Spares & Accessories (Not Supplied):

POLARIZATION INDEX (PI) & DIELECTRIC ABSORPTION RATIO (DAR) Insulation is sensitive to temperature and humidity variations. In addition, measurement is affected by the appearance of disturbance currents. To overcome these effects, long-term measurements must be performed and the PI and DAR coefficients must be calculated. They will then allow qualification of the insulants and their ageing.
 
DIELECTRIC DISCHARGE INDEX (DD) This test measures the dielectric absorption of a heterogeneous or multi-layer insulant and will reveal the presence of impurities or a faulty layer.
 
Var 50-5,000 V SETTING To deal with the whole range of measurement situations (electrical equipment, telecom installations, etc.) and measure as accurately as possible, all 3 instruments offer the possibility of selecting the test voltage by means of the Var 50-5,000 V setting on the rotary switch. The voltage can be adjusted between 40 V and 1,000 V in 10 V increments and between 1,000 V and 5,100 V in 100 V increments.
 
PROGRAMMABLE ALARMS A high or low alarm threshold can be memorized. If there is an overrun, a visual warning is triggered and a buzzer sounds.
 
STORAGE (C.A 6547 and C.A 6549) The C.A 6547 and C.A 6549 have an internal memory for storing several thousand measurements. Storage is performed with two indices, OBJ (object) and TEST (test), which store the results in an ordered way.
 
STEP VOLTAGE (C.A 6549) The resistance of a faulty insulant gradually decreases as the test voltage rises. This test, which involves increasing the test voltage in steps, can be used to assess the quality of the insulant by observing the curve R(Utest) and the result in ppm/V which provides a quantitative evaluation of the curve's slope.
 
TEST WITH PROGRAMMABLE DURATION Insulation measurements sometimes take a long time to stabilize because of transient disturbance currents. By carrying out long-term measurements and analysing the trend curve of the insulation according to the test voltage application time, you can obtain a better assessment of insulant quality.
 
GRAPH R(t) If a programmed-duration test is carried out, the instruments automatically store the samples concerning the insulation tested, at the rate chosen by the user. The curve R(t) can be plotted by hand on the basis of the results, or on screen via the DATAVIEWER software. With the C.A 6549, it is also possible to view the curve directly on the graphic screen.
 
SMOOTH FUNCTION When the measurements are unstable, the Smooth function can be used to smooth the display of the insulation values so that they are easier to read and can be interpreted more quickly
 
PRINTER (C.A 6547 and C.A 6549) A compact serial printer can be connected for direct printouts on site. It is also possible to use a desktop parallel printer with a series/parallel adapter available as an accessory
 
REFERENCE TEMPERATURE (C.A 6549) The value of an insulation resistance varies according to the measurement temperature. For accurate, reliable monitoring, it is always a good idea to express a measurement result in terms of a reference temperature. By simply pressing a button, the calculation can be performed automatically by the instrument.
 
DATAVIEW SOFTWARE This software recovers the stored data, plots the trend curve R(t), prints the customized test protocols, and creates files for spreadsheet software. DataView can also configure and control the instrument via an RS232 link!
