Megger DELTA4000 Series 12 kV Insulation Diagnostic System

Megger DELTA4000 Series 12 kV Insulation Diagnostic System

The Megger DELTA4000 Series is a 12 kV insulation diagnostic system that measures power factor, tan delta, capacitance and related losses to assess the condition of high-voltage insulation. Combining a variable-frequency (DFR) source with patented Individual Temperature Correction (ITC) and advanced noise suppression, it delivers dependable results even in the electrically noisy environment of an energised substation. A two-piece modular design keeps each case light enough for one person to handle, while PowerDB and Delta Control software automate testing, temperature correction and reporting for transformers, bushings, cables, circuit breakers, arresters and rotating machines.

Key features of the Megger DELTA4000 Series 12 kV test set

• 12 kV, 300 mA output – up to 12 kV AC test voltage with 300 mA output current for testing a wide range of apparatus.
• Variable-frequency DFR (1–500 Hz) – narrowband dielectric frequency response, including 1 Hz testing, for deeper insulation condition assessment beyond line frequency.
• Patented Individual Temperature Correction (ITC) – calculates the actual temperature dependence of the tested insulation instead of applying generic correction tables.
• Powerful noise suppression – handles up to 15 mA interference current or a 1:20 signal-to-noise ratio for reliable results in live substations.
• Comprehensive measurements – capacitance, power factor / dissipation factor, tan delta, watts loss, inductance, voltage and current, plus Voltage Dependence Factor (VDF) detection.
• Two-piece modular design – separate 14 kg and 22 kg cases simplify shipping and one-person field handling.
• PowerDB & Delta Control software – automatic testing, temperature correction and reporting over USB or Ethernet.
