HIOKI 3455 HIGH VOLTAGE INSULATION HiTESTER

HIOKI HIGH VOLTAGE INSULATION HiTESTER 3455
5kV High Voltage Digital Insulation Resistance Tester
Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The 3455 is a 5-range, 250V to 5000V digital insulation resistance tester with bargraph, built-in memory, leak current and voltage testing, and DAR and PI calculation capabilities to help shorten work time associated with field insulation testing.

Overview

• Measure insulation of high-voltage equipment (such as transformers, cables, and motors)
• Wide testing voltage range, up to 5.00 kV from 250 V DC
• Adjustable testing voltage in 25 V steps up to 1 kV, and 100 V steps from 1 kV to 5 kV
• Wide measurement insulation range, up to 5 TΩ (at 5 kV testing voltage, 1 TΩ=10^12 Ω)
• Diagnose the insulation of various equipment with the built-in memory for data storage
