Transformer Comprehensive Test Bench for Power and Distribution Transformers – Automatic Transformer Testing System for Factory Routine and Acceptance Tests

The Transformer Comprehensive Test Bench provides an integrated solution for electrical performance testing of power transformers and distribution transformers.

Designed for transformer manufacturing plants and testing facilities, the system brings several routine tests together in one platform, helping engineers improve testing efficiency while maintaining consistent measurement procedures.

A comprehensive transformer testing system may include ratio testing, winding resistance, no-load characteristics, load characteristics, short-circuit impedance and withstand voltage testing.

• Transformer factory routine testing
• Factory acceptance testing
• Incoming inspection
• Transformer commissioning
• Maintenance testing
• Preventive testing
• Laboratory testing
• Transformer production line testing

Measures transformer turns ratio, ratio error and vector group.

Checks winding resistance and can help identify winding connection problems, poor contacts and tap-changer contact abnormalities.

Measures:

• No-load current
• No-load loss
• Power factor
• Core-related electrical characteristics

Measures:

• Load loss
• Short-circuit impedance
• Load current
• Relevant power parameters

The system can be configured for power-frequency AC withstand and induced voltage testing.

A conventional transformer factory may use several separate instruments. This can mean repeated wiring, repeated setup and manual data consolidation.

An integrated system can simplify the workflow and provide centralized control and data management.
