Automatic Transformer Comprehensive Test Bench for Turns Ratio, Winding Resistance, No Load Loss, Load Loss and Withstand Voltage Testing

The Automatic Transformer Comprehensive Test Bench is an integrated testing platform designed to perform multiple routine and diagnostic tests on power and distribution transformers.

Instead of using multiple independent instruments and repeatedly changing test connections, an integrated test bench combines measurement, control, protection, data acquisition and reporting functions into one coordinated system. Current commercial systems commonly integrate ratio/vector group, DC winding resistance, no-load loss, load loss, insulation and withstand-voltage testing.

• Transformer turns ratio test
• Vector group test
• Winding DC resistance test
• No-load loss test
• No-load current test
• Load loss test
• Short-circuit impedance test
• Insulation resistance test
• Power-frequency withstand voltage test
• Induced withstand voltage test
• Temperature rise test
• Capacitance and tan delta test
• Partial discharge test, depending on configuration

• Power transformer manufacturers
• Distribution transformer manufacturers
• Transformer repair workshops
• Electrical testing laboratories
• Power utilities
• Transformer inspection departments
• Factory acceptance testing

Multiple standalone instruments: repeated wiring and setup increase testing time.

Manual calculation: increases the possibility of recording and calculation errors.

Fragmented test data: makes final reports difficult to organize.

An integrated platform addresses these issues through centralized control and data management.
