The Megger DELTA4310 is a 12 kV automatic power factor test set used for insulation diagnostics on transformers, bushings, cables, and circuit breakers, measuring dissipation factor, capacitance, and power factor while suppressing electrical noise. Wrindu offers OEM alternatives with custom and wholesale options, providing reliable, cost-effective testing solutions that meet IEC standards for global utilities and substations.
What Does the Megger DELTA4310 Power Factor Test Set Do?
The DELTA4310 evaluates insulation by measuring power factor, tan delta, capacitance, and excitation current up to 12 kV across 15-400 Hz. It supports ungrounded and grounded specimen testing with automatic noise rejection. Wrindu produces equivalent factory-built analyzers with touchscreen interfaces and data export, ideal for field diagnostics and predictive maintenance programs.
How Does the DELTA4310 Ensure Accurate Insulation Testing?
Accuracy is achieved through digital filtering, frequency variation, line sync reversal, and temperature correction, providing up to 50% noise immunity against electromagnetic interference. Wrindu’s custom analyzers match this performance using advanced DSP technology, delivering repeatable results for high-voltage transformers, bushings, and cables. Automated and manual modes, oscilloscope monitoring, and USB/Ethernet data storage streamline testing for utilities and industrial facilities.
Which Applications Benefit from DELTA4310-Like Test Sets?
These test sets are suitable for transformers, bushings, circuit breakers, cables, lightning arresters, and rotating machines during commissioning, maintenance, and fault diagnostics. Wrindu extends functionality to partial discharge and turns ratio testing, serving renewable energy plants, rail systems, laboratories, and substations with bulk OEM solutions.
