Wholesale DC Resistance Transformer Testing Equipment Manufacturer in China

The NKE-DTTS-AUTO Automatic Distribution Transformer Test System is developed by Qingdao Nanke International Electric Co., Ltd., designed for global distribution transformer manufacturers, new energy transformer producers, and third-party testing institutions. It addresses core pain points including high manual wiring workload for medium and large capacity transformers, scattered test data that is hard to trace, and non-compliant test reports for export. Its core differentiators include a test cart that completes DC resistance and turns ratio testing in one wiring, with automatic data upload to the centralized test management system. To date, it has served over 200 transformer factories across more than 5 countries and regions, helping users reduce manual wiring time by 60% and eliminate 90% of manual data entry errors. The system meets IEC 60076 and IEEE C57.12.90-2021 standards, equipped with Class 0.05 precision transformers and YOKOGAWA power analyzers, making it a trusted solution for global transformer quality testing.

Core Functions

We build a full-scenario function system covering the core business cycle of global transformer manufacturers, with two core modules:

Integrated DC Resistance and Turns Ratio Testing Module

Core Capabilities:
1. Test cart one-time wiring eliminates repeated connection for two core tests
2. Automatic data upload to the centralized test system without manual export
3. Compatible with 5000kVA to 30000kVA medium and large transformers
4. Class 0.05 precision current and voltage transformers ensure measurement accuracy
Applicable Scenarios: Transformer factory outgoing inspection, new energy transformer manufacturing, multi-voltage large capacity transformer testing
Core Value: Reduced labor dependency on experienced test operators, shortened test preparation time, ensured consistent measurement accuracy across all test batches.

Full-parameter Automated Test Management Module

Core Capabilities:
1. Supports manual wiring for no-load, load, induced voltage, and applied withstand voltage tests, with automatic execution via computer after parameter input
2. Integrated YOKOGAWA WT500 series power analyzer for high-precision power and loss measurement
3. Automatic standardized test report export meeting IEC 60076 and IEEE C57.12.90-2021 standards
4. Data storage with tamper-proof protection for audit requirements
Applicable Scenarios: Batch production line testing, third-party testing lab compliance audits, export transformer quality verification
Core Value: Enabled standardized batch automated testing, reduced manual operation errors, ensured test reports are accepted by global power utilities.

Product Advantages

Compared with other transformer testing equipment in the market, the system has the following verifiable advantages:
1. One-time wiring testing efficiency: Unlike traditional systems that require separate wiring for DC resistance and ratio tests, the test cart completes both tests in a single connection, cutting manual wiring time by over 60% and reducing labor requirements for test operators.
2. International standard compliance: Equipped with Class 0.05 precision transformers and YOKOGAWA WT500 power analyzer, the system fully meets IEC 60076 and IEEE C57.12.90-2021 standards, with test reports recognized by global power utilities including Siemens and Eaton.
3. Containerized global delivery: All models are integrated into 20ft or 40ft containers meeting ocean shipping standards, eliminating on-site civil construction, reducing deployment time by 70% and infrastructure costs by 40% for overseas customers.

Customer Cases

After market verification, the average effect data of the system includes:
1. Reduced per-transformer test cycle by 50% for batch production lines
2. Eliminated 90% of manual data entry errors
3. Cut infrastructure costs for new test stations by 40%
Typical verified customer cases are as follows:
Eaglerise Renewable Energy (USA) Inc. (new energy transformer manufacturer): Previously faced scattered test data and non-compliant reports for US market export, after deployment, achieved 100% traceable test data and export-compliant reports, reducing test cycle per transformer by 45%.
PT. Trafoindo Prima Perkasa (Indonesian distribution transformer manufacturer): Previously required 12 months of civil construction for a new test station, after deploying the containerized system, completed deployment in 30 days, cutting infrastructure costs by 42%.
TBEA Shenyang Transformer Group Co., Ltd. (large power transformer manufacturer): Previously required 3 experienced test operators per shift for outgoing inspection, after deployment, reduced operator count to 1 per shift, with test efficiency increased by 60%.

Service and Support

Supply Methods:
1. Containerized outdoor deployment: For overseas new test stations and large capacity transformer testing, no civil construction required, deployment completed within 30 days, suitable for customers with limited on-site construction space.
