Insulation tester CA 6550

voltageresistancefor electrical installations

With its site-proof casing, the C.A 6550 insulation tester is used to check equipment insulation during manufacturing, on-site installation work, periodic inspections and recommissioning of installations. It is ideal for electricity companies, manufacturers, installers, maintenance firms, industry, R&D centres and infrastructure. 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 insulation testing at 5-10 kV. Functions and specifications: •Wide measurement range from 10 kΩ to 25 TΩ •Fixed or programmable test voltage from 40V to 10 kV •5mA max. charging current •Large backlit LCD screen with digital display, bargraph and R(t)+u(t), i(t) and i(u) graphs •Automatic ratio calculation: DAR / PI / DD / DR (ppm/V) •Multiple test modes: voltage ramp and step with "burning", "early break" and "I-limit" modes •Filters to optimize measurement stability •Calculation of R at a reference temperature •80,000-measurement storage capacity and real-time clock •Optically-isolated USB communication for transfer onto PC and report generation with DataView® software •Power supply NiMH rechargeable battery with external charger •Compliant with IEC 61557 -1 -2 •Electrical safety: IEC 61010 1000V CAT IV •Dimensions: 406 x 330 x 174 mm / 6 kg
