Chauvin C.A 6555 15,000V Insulation Tester

The Chauvin Arnoux C.A 6555 megohmmeter is a high-end portable measuring instrument 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. The Chauvin C.A.6555 makes insulation measurements at voltages up to 15,000V. Thanks to the large measurement range, extending up to 30 TΩ, the Chauvin C.A6555 meets the requirements of companies manufacturing cables, transformers, rotating machinery and medium-voltage generators, as well as professionals in the Electricity Transmission and Distribution sector. Specially adapted for checking insulation on rotating machinery with a 12 kV power supply or higher, the C.A 6550 complies with the IEEE43 standard which recommends testing insulation at 5-10 kV. 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.
