DELTA 4000 Series 12 kV Insulation Diagnostic System is a fully automatic 12 kV insulation power factor / dissipation factor (tan delta) 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.

DELTA 4000 Series 12 kV Insulation Diagnostic System:

  • Power factor test set
  • Automatic and manual operation
  • Accurate and repeatable measurement results with high noise suppression
  • Lightweight, rugged two-piece design
  • New built-in intelligent temperature correction (patent pending)
  • New automatic voltage dependence detection (patent pending)
  • Portable, lightweight, and rugged two-piece design

The DELTA4000 Series operates with Power DB software for
automatic testing and reporting or with Delta Control software for
real-time manual testing. The test set is designed to provide a comprehensive AC insulation
diagnostic test. The high power variable frequency design generates
its own test signal independent of line frequency quality and the
hardware design uses the latest technology available for digital
filtering of the response signal. As a result, the DELTA4000 Series
produces reliable results and stable readings in the shortest time
with the highest accuracy, even in high interference substations.
