Insulation Tester
Description
An Insulation Tester, commonly known as a Megger, is an electrical testing instrument used to measure the insulation resistance of cables, wires, and electrical equipment. It helps in detecting leakage currents and ensures safety and proper functioning of electrical systems.
Parts
- Display: Shows insulation resistance values.
- Test Leads: Connect the tester to the circuit.
- Control Switch: Selects test voltage and functions.
- Internal Generator: Produces high DC voltage for testing.
- Housing: Protects internal components.
