Chauvin C.A 6550 10KV Insulation Tester

The Chauvin Arnoux C.A 6550 megohmmeter is a high-end portable measuring instruments intended for the measurement of very high electrical insulation and resistance values, mounted in a rugged site housing with a cover; it has a graphic screen and can operate on battery or mains power. With its site-proof casing, the Chauvin C.A 6550 insulation tester is used to check equipment insulation during manufacturing, on-site installation work, periodic inspections and recommissioning of installations. Specially adapted for checking insulation on rotating machinery with a 12 kV power supply or higher, the Chauvin C.A6550 complies with the IEEE43 standard which recommends insulation testing at 5-10kV. FEATURES Wide measurement range from 10 kΩ to 30 TΩ. Fixed or programmable test voltage from 40 V to 10/15 kV. 5 mA charging current. Large backlit LCD screen with digital display, bargraph and R(t)+u(t), i(t) and i(u) graphs. Automatic calculation of DAR / PI / DD /?R (ppm/V) ratios. Multiple test modes: voltage ramp and step with “burning”, “early break” and “I-limit” modes. 3 filters to optimise measurement stability. Calculation of R at a reference temperature. Storage of 80,000 measurements and Real-time Clock. Optically-isolated USB communication for transfer onto PC and report generation with the DataView® software.
