Power Factor Test Sets

Megger DELTA4000 Series

Megger DELTA4000 Series

The DELTA4000 Series is an exceptionally compact and lightweight Tan Delta that has a raft of novel and unique features to commend it, including a patented swept frequency concept to allow temperature effects to be negated in the measurement.  The Delta 4000 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 (an optional TTR capacitor is available)
