Insulation Resistance Meters from Megger

  • Uncategorized

Weathering, manufacturing defects, electrical stress and equipment handling are some of the common causes of insulation deterioration. It is a good idea to always assess the condition of electrical insulators to prevent problems from getting worse. Problems caught early can save you a lot of money and effort. If a defect develops and you do not catch it early, the electrical component may eventually break down. It costs less to recondition a part and extend its operating life than to replace the whole component. 

Insulation resistance is one of the common methods of testing insulation condition. This test allows you to determine when to schedule a repair or replacement. An electrical insulator in good working condition should be able to resist the current flowing in the main conductor. However, when defects like chaffing, cracking and moisture accumulation develops, the resistance decreases and current flows. When this happens, arcs may form outside the insulator which may cause electrical shock to personnel, further deterioration of electrical components or fire. Just think of the hassle you’ll go through because of lack of regular maintenance. 

Megger Test Equipment offers a selection of insulation resistance testers to help you diagnose insulation problems in an electrical system. The Megger MIT300 family of insulation testers offers durable construction, excellent safety features and a continuity test function. Some models also offer additional features that allows thorough diagnostics of the insulator and surrounding parts.
