Haefely Technology 5478

The 5478 is a digital multipurpose tester intended for testing, analyzing, inspecting and periodic maintaining of any high voltage insulations. This instrument offers a complete set of functions to measure and detect effectively all parts of current in an insulation system. The instrument can supply an output power of 5 W and a test voltage of up to 5000 V and therefore measure insulation resistances up to 5 TOhm. Additionally step-up voltage measurement, withstand voltage measurement, AC/DC voltage and frequency measurements up to 600V can be performed.
