Megger 12 Kv Insulation Diagnostic System
Model No :
Megger DELTA4110
Part Code :


The Megger's DELTA4000 Series is a fully automatic 12 kV insulation power factor/dissipation factor (tan∂) test set designed for condition assessment of electrical insulation in high voltage apparatus such as transformers, bushings, circuit breakers, cables, lightning arresters and rotating machinery. In addition to performing insulation power factor tests, the DELTA4000 Series can be used to measure the excitation current of transformer windings as well as to perform automatic tip-up tests and HV turns-ratio testing.

- Wide frequency test voltage (1-500 Hz), includes DFR diagnostic capability
- Accurate measurement results under high noise conditions as tested to 765 kV substations
- Lightweight, rugged two-piece design
- Patented built-in individual temperature correction eliminates the need for temperature correction tables
- Industrial 300 mm (12 in.) touch-screen controller
