Insulation Resistance Testers (Megohmmeters)

Insulation Resistance Testers (Megohmmeters)

Insulation resistance testers, also known as megohmmeters, are essential instruments for verifying the integrity of electrical insulation. By applying test voltages from 1000V to 15kV, these instruments measure the resistance of insulation materials, ensuring systems remain safe, reliable, and compliant with electrical standards. Whether you are an electrician, industrial engineer, or utility technician, insulation testing is critical for preventing failures and downtime.

Why Insulation Resistance Testing Matters

Electrical insulation naturally degrades over time due to heat, moisture, contamination, and mechanical stress. Without regular testing, insulation failure can cause costly equipment damage, unplanned outages, or even safety hazards. Using a professional insulation tester allows early detection of problems and ensures compliance with international electrical safety standards.

Applications

  • Contractors: Testing insulation during installations and maintenance.
  • Utilities: Routine verification of cables, transformers, and switchgear.
  • Industrial plants: Preventive maintenance on motors, generators, and high-voltage equipment.
  • Engineers: Advanced insulation analysis for reliability and compliance.

Types of Insulation Testers

  • 1000V insulation testers: Compact models for everyday electrical work.
  • 2.5kV & 5kV insulation testers: Professional-grade instruments for industrial testing.
  • 10kV+ insulation testers: High-voltage testers for critical infrastructure and advanced applications.

Choosing the Right Tester

The right insulation tester depends on your application. Contractors may only need a 1000V meter for daily jobs, while utilities and engineers often require 5kV or 10kV testers for high-voltage equipment. All our instruments are designed for accuracy, durability, and ease of use in the field.
