I. Project Overview

This project is the third semi-automatic intelligent transformer testing system delivered by Nanke Electric to PT. Trafoindo Prima Perkasa (TRAFINDO) in 2025. The customer’s headquarters is located in Jakarta, Indonesia. Founded in 1981, TRAFINDO is a leading local transformer manufacturer and the largest producer of distribution transformers in Indonesia. This system is custom-designed for the customer’s dry-type transformer production line, capable of performing routine pre-delivery tests with intelligent operation and precise data, effectively optimizing the quality inspection process and significantly improving production line testing efficiency.

II. Maximum Testing Capacity

34.5/0.4 kV dry-type transformers: capacity ≤ 15,000 kVA, impedance 4%–14%

6/0.4 kV dry-type transformers: capacity ≤ 10,000 kVA, impedance 4%–14%

Maximum loss handling capacity: 180 kW

III. Test Items

1. Measurement of no-load loss and no-load current of transformers

2. Calculation of no-load current percentage of transformers

3. Measurement of load loss of transformers and standard temperature conversion (at 100% current)

4. Measurement of short-circuit impedance of transformers and standard temperature conversion

5. Induced withstand voltage test for transformers

6. Power-frequency withstand voltage test for transformers

7. Partial discharge test for transformers

IV. Project Highlights

1. Customized Adaptation: Aligned with Indonesian production and quality inspection standards, compatible with the customer’s dry-type transformer production line, seamlessly integrating into existing production processes.

2. High Efficiency and Time-Saving: Load and no-load tests can be connected with a single wiring setup, eliminating repeated disconnection and reconnection, greatly enhancing testing efficiency.

3. Intelligent and Convenient: Intuitive interface, real-time data visualization, customizable test report photos, automatic generation of standard reports, and simple operation.

4. Comprehensive Services: One-stop service covering design, installation, commissioning, and training, ensuring rapid implementation and stable operation.

5. Compact Layout: Modular integrated design, saving factory space and adapting to existing premises.
