I. Project Overview

Nanke Electric customized this semi-automatic intelligent transformer testing system for PT. Trafoindo Prima Perkasa, a leading transformer manufacturer in Indonesia. This is the fifth set of specialized testing equipment delivered to them in 2024, precisely meeting the customer's factory quality inspection needs for large-scale production of dry-type distribution transformers. The core objective is to achieve precise testing of higher-voltage, larger-capacity dry-type transformers, adapting to the customer's upgraded product testing requirements.

II. Maximum Testing Capacity

34.5/0.4 kV, 15,000 kVA and below dry-type transformers (impedance 4%–14%)

6/0.4 kV, 10,000 kVA and below dry-type transformers (impedance 4%–14%)

III. Test Items

(1) Measurement of transformer no-load loss and no-load current

(2) Calculation of transformer no-load current percentage

(3) Measurement of transformer load loss and standard temperature conversion (at 100% rated current)

(4) Measurement of transformer short-circuit impedance and standard temperature conversion

(5) Transformer induced voltage withstand test

(6) Transformer power frequency withstand test

(7) Transformer partial discharge test

IV. Project Highlights

(1) Semi-automatic phased wiring, flexible operation, compatible with the customer's existing production process

(2) Integrated high-precision measurement components, stable and reliable data, compliant with industry testing standards

(3) Support for customized test reports, aligned with the customer's production management system

(4) Mature solution with rapid delivery, providing one-stop on-site services including installation, commissioning, and operator training
