Product Overview
The NKE-DTTS-AUTO/5000 fully automatic distribution transformer testing system belongs to the NKE-DTTS-AUTO series of fully automatic testing equipment, specifically designed for batch factory acceptance tests of small and medium-sized medium- and high-voltage distribution transformers, strictly adhering to both IEC 60076 and IEEE C57.12.90-2021 international standards. The equipment can accommodate dry-type and oil-immersed transformers with a maximum voltage rating of 38.5 kV and a capacity of 5000 kVA, comprehensively covering all factory acceptance test requirements for single-phase transformers up to 500 kVA and three-phase transformers up to 10,000 kVA, spanning the full range of voltages from 4.16 kV to 38.5 kV.
The entire system features an integrated cabinet design, highly consolidating the variable-frequency power supply, intermediate transformer, high-precision measurement system, and intelligent selector switch into a compact structure that is easy to deploy. Equipped with industry-standard hardware, including 0.05-class precision current and voltage transformers and Yokogawa WT500 or higher‑model power analyzers, it ensures accurate and compliant test data. Relying on the core operating mode of **single wiring, fully automatic testing**, combined with a four‑station automated operation design, a single operator can complete batch testing, automatically process data, generate and export standard factory acceptance test reports, while also providing 24/7 technical support and free quotation assistance—making it an efficient, standardized testing solution for transformer manufacturing, quality inspection, and certification scenarios.
Operating Principle
The equipment integrates power supply, voltage regulation, measurement, and intelligent switching functions into a unified system, establishing a standardized, fully automatic testing hardware platform suitable for all voltage and capacity levels of distribution transformers up to 38.5 kV;
For testing, only a one-time standard wiring is required; the system automatically switches between various test circuits via its built-in intelligent selector switch, eliminating the need for manual disconnection and reconnection, thereby greatly simplifying the traditionally cumbersome operational process;
After starting the program, the computer automatically completes all factory acceptance test items—including DC resistance, turns ratio, insulation, losses, and dielectric strength tests—in sequence, operating entirely without human intervention;
Leveraging 0.05-class high-precision measurement components to collect, calibrate, and compute test data in real time, the system automatically generates standardized factory acceptance test reports upon completion, achieving paperless, low-error, traceable, fully automatic testing throughout the entire process.
Core Test Items
Standard default test items: DC resistance test, turns ratio test, insulation resistance test, no-load loss test, load loss test, induced voltage withstand test, power frequency withstand test
