What is the difference between tan delta test and megger test?

Tan delta testing, also known as dissipation factor (PF) testing, or loss angle testing or dielectric dissipation factor（DDF) , is a diagnostic method used to measure dielectric loss/dissipation factor(tgδ) and capacitance (Cx) and evaluate the insulation condition of electrical equipment, such as cables, transformers, capacitors, and rotating machines.
