I. Project Overview
This project is custom-built by Nanke Electric for PT. Trafoindo Prima Perkasa, and it is the customer's 8th semi-automatic intelligent transformer testing system purchased in 2025. The system is primarily used for factory acceptance tests of dry-type distribution transformers. It adopts a staged wiring method for load and no-load conditions, balancing test accuracy with operational convenience to meet the customer's needs for large-scale, high-efficiency production quality inspections.
II. Maximum Testing Capacity of This Project
34.5/0.4 kV, dry-type transformers with ratings up to 15,000 kVA and impedance ranging from 4% to 14%;
6/0.4 kV, dry-type transformers with ratings up to 10,000 kVA and impedance ranging from 4% to 14%;
Maximum loss: 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 conversion to standard temperature (at 100% current)
(4) Measurement of short-circuit impedance of transformers and conversion to standard temperature
(5) Induced voltage withstand test of transformers
(6) Power frequency withstand test of transformers
(7) Partial discharge test of transformers
IV. Project Highlights
Semi-automatic staged wiring, offering flexible operation and compatibility with the customer's existing production processes
Integration of high-precision measuring instruments, ensuring stable and reliable data that meets international and Indonesian local standards
