isolasjonstester
Isolasjonstester, also known as insulation testers or megohmmeters, are specialized electrical instruments used to measure electrical resistance, specifically the resistance of an electrical insulator. They are designed to apply a high voltage, typically 50V, 100V, 250V, 500V, or 1000V, to the insulation being tested and measure the resulting current flow. A higher resistance indicates good insulation, while a low resistance suggests a potential fault or degradation of the insulating material.
These testers are crucial for ensuring electrical safety and the reliability of electrical equipment. By performing
When conducting an insulation resistance test, the tester is connected between a live conductor and a grounded
