NKEDTTSAUTO DC Resistance Transformer Testing Equipment for Makers

The NKE-DTTS-AUTO Automatic Distribution Transformer Test System is developed by Qingdao Nanke International Electric Co., Ltd., a specialized manufacturer of power equipment testing solutions. Designed for global distribution transformer manufacturers, new energy transformer producers, and third-party testing laboratories, the system addresses core pain points including exponentially increasing wiring workload for medium-to-large transformers, scattered test data that hinders traceability, and difficult transportation of bulky test equipment. Its core differentiators include a test trolley that completes DC resistance and ratio testing with a single wiring setup, and containerized integration that meets ocean shipping standards. To date, the system has been deployed for over 200 transformer factories across more than 5 countries including the United States, Mexico, Indonesia, South Korea, and Thailand. It helps users reduce test cycle time by over 60% and cut testing labor costs by 40%, fully complying with IEC 60076 and IEEE C57.12.90-2021 international standards, making it a trusted solution for global power equipment testing needs.

Core Pain Points and Solutions

Core Functional Modules

The system is built around the full testing workflow of global transformer manufacturers, with two core modules:
1. Integrated DC Resistance and Ratio Testing Module: Core capabilities include single wiring setup via test trolley for DC resistance and ratio testing, automatic data transmission to the central test system, compatibility with 5000kVA to 30000kVA transformers, and integration with Class 0.05 precision current and voltage transformers. This module is applicable for transformer factory outgoing inspection, new energy transformer manufacturing, and multi-voltage large-capacity transformer testing, delivering 70% reduction in pre-test wiring time and lower reliance on senior testing personnel.
2. Automated Routine Test Execution Module: Core capabilities include manual wiring for no-load, load, induced overvoltage, and applied overvoltage tests with automatic computer-controlled execution, one-click test initiation, automatic data recording and standardized report export, compliance with IEC 60076 and IEEE C57.12.90-2021 standards, and integration with YOKOGAWA WT500 series power analyzers. This module is applicable for batch production line testing, export transformer compliance verification, and third-party laboratory testing, shortening full test cycle by over 60% and reducing labor costs by 40%.

Key Product Advantages

Compared to traditional transformer testing equipment, the NKE-DTTS-AUTO offers three core differentiators:
1. Single-wiring automated workflow: Unlike traditional systems that require repeated wiring for DC resistance, ratio, and routine tests, the test trolley design cuts wiring time by over 70% and reduces required testing personnel by half.
2. Ocean-ready containerized design: All models are integrated into standard 20-foot or 40-foot containers, eliminating on-site assembly needs and reducing transportation damage risk by 60% compared to disassembled delivery.
3. International standard compliance: Equipped with Class 0.05 precision transformers and YOKOGAWA power analyzers, the system generates test reports accepted by global power grid operators and certification bodies.

Verified Customer Results

Across global deployments, the system delivers average measurable results including 62% shorter test cycles, 45% lower testing labor costs, and 100% data traceability compliance for export-oriented manufacturers. Typical customer cases include:
1. Eaglerise Renewable Energy (USA) Inc., a new energy transformer manufacturer: Previously faced high wiring workload for 10000kVA wind transformers and compliance delays for US market entry. After deployment, reduced wiring time by 72%, achieved full data traceability, and cut test report preparation time by 58%.
2. PT. Trafoindo Prima Perkasa, an Indonesian distribution transformer manufacturer: Struggled with 3-month on-site deployment delays for imported test equipment. After receiving the containerized system, completed deployment in 12 days and started batch testing within 2 weeks.
