What is Megger ?Megger DefinitionA megger is defined as a device used to measure the insulation resistance of electrical components and systems, crucial for ensuring operational safety and functionality.Working PrincipleMeggers generate a testing voltage (either via a hand-cranked generator or battery) that creates a torque proportional to voltage and inversely proportional to current, helping measure the electrical resistance.Types of MeggersElectronicAdvantages Level of accuracy is very high.
