Fluke insulation testers are widely recognised in the electrical industry. Many professionals search by brand when they need a dependable megohmmeter for commissioning or maintenance work. If you are assessing options in this category, consider professional alternatives designed for accuracy, durability, and high-voltage testing from 1kV to 15kV.

Insulation Testing at a Glance

Insulation resistance testing verifies the condition of cables, motors, switchgear and other assets by applying a DC test voltage and measuring resistance. Routine testing helps identify moisture ingress, contamination, or ageing insulation before failures occur.

Who Uses These Instruments?

  • Contractors: Commissioning and verification of new installations.
  • Industrial maintenance: Scheduled testing of critical equipment.
  • Utilities: Periodic checks on high-voltage systems and distribution networks.
  • Engineers: Diagnostic assessments as part of reliability programs.
