I. Project Overview

This project is custom-built by Nanke Electric for PT. Trafoindo Prima Perkasa, representing the customer's 8th semi-automatic intelligent transformer testing system purchased in 2025. It is primarily used for factory acceptance tests of dry-type distribution transformers. The system 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 up to 15,000 kVA with impedance ranging from 4% to 14%;

6/0.4 kV, dry-type transformers up to 10,000 kVA with impedance ranging from 4% to 14%;

Maximum loss: 180 kW

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 conversion to standard temperature (at 100% current)

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

(5) Transformer induced voltage withstand test

(6) Transformer power frequency withstand test

(7) Transformer partial discharge test

IV. Project Highlights

Semi-automatic staged wiring ensures flexible operation, seamlessly integrating with the customer's existing production workflow

Integration of high-precision measuring instruments delivers stable and reliable data, fully compliant with international and Indonesian local standards

Customizable test reports compatible with the customer's production management system

Mature solutions enable rapid delivery, accompanied by on-site commissioning and training services provided as a one-stop solution
