Introduction:

The most important reason to perform an insulation test is to ensure public and personal safety after the initial installations of electrical systems (cables, transformers, control panels ….. ) It also protect and prolong the life of electrical systems and motors especially when performing periodic maintenance and detects the accumulation of dust and dirt which leads to insulation failure and thus fires

 

Definition The electrical insulation test is a measure of the resistance of the DC current and it can be performed for all electrical equipments that have insulation materials such as cables, transformers …
  • The main goals of the insulation test:
  • Detecting current leakage
  • Detecting insulation defects that reduce the resistance
  • Ensuring the quality and efficiency of the electrical circuits and system integrity
