CAT IV 1,000 V Voltage Absence Testers (VATs) STANDARDS Voltage Absence Testing: a clearly-defined procedure In the context of work on installations connected to the electricity distribution network, the standards stipulate that the measurements must be performed with the power off to avoid electrical hazards (EN 50110-1 standard, DIN VDE 0682-401, NF C 18-510, etc.). To secure the installation and ensure that it is non-current-carrying, there is a procedure called Separation which imposes the use of a Voltage Absence Tester. CA 771 & CA 773: beyond the standard recommendations • A...

APPLICATIONS Voltage up to 1,000 Vac / 1,400 Vdc at up to 800 Hz The specifications of the CA 771 and CA 773 mean they can be used for work on all LV electrical networks, whether they are electricity distribution networks or the more specific networks encountered in naval or aviation applications. Climatic conditions The type-S extended climatic class allows use in extreme temperature conditions. This means it offers an operating range from -30 °C to +60 °C for applications such as: • Installations at altitude (mountains, etc.), underground installations, etc. • Refrigeration installations,...
