Complete Transformer Test Equipment Solutions

Transformer testing involves multiple diagnostic methods to evaluate different electrical characteristics and operating conditions. Weshine offers a comprehensive range of transformer testing instruments for laboratory testing, production inspection, commissioning, and field maintenance.

Transformer Turns Ratio Tester

The Transformer Turns Ratio Tester is designed to measure the transformation ratio of power transformers and verify whether the winding ratio meets design requirements.

It is commonly used for:

• Transformer manufacturing quality inspection
• Tap changer performance verification
• Transformer commissioning testing
• Routine maintenance diagnosis

Accurate turns ratio measurement helps detect winding connection errors, short circuits, and abnormal transformer conditions.

Transformer DC Winding Resistance Tester

The Transformer DC Winding Resistance Tester is used to measure transformer winding resistance and evaluate the condition of winding connections and conductive paths.

Applications include:

• Detecting winding defects
• Checking tap changer contact conditions
• Evaluating connection reliability
• Supporting transformer maintenance testing

High-precision resistance measurement provides important data for transformer condition assessment.

CT PT Measurement and Analysis Equipment

The CT PT Measurement and Analysis Equipment is designed for testing current transformers (CT) and potential transformers (PT) used in power systems.

These instruments support:

• CT/PT ratio testing
• Excitation characteristic analysis
• Polarity verification
• Burden testing
• Protection accuracy evaluation

They are widely applied in substations, power utilities, and electrical testing laboratories.

Transformer Tan Delta Tester

Transformer insulation performance is a key factor affecting equipment reliability. A Transformer Tan Delta Tester evaluates insulation dielectric characteristics by measuring dielectric loss and capacitance values.

It helps engineers:

• Assess insulation aging
• Detect moisture contamination
• Evaluate insulation degradation
• Improve preventive maintenance decisions

Tan delta testing is widely used for transformers, bushings, and other high-voltage insulation systems.

Transformer Capacity and Loss Tester

The Transformer Capacity and Loss Tester is used to measure transformer operating parameters including no-load loss, load loss, impedance voltage, and capacity-related characteristics.

Typical applications include:

• Transformer factory acceptance testing
• Energy efficiency evaluation
• Performance verification
• Quality control inspection

Accurate loss measurement helps manufacturers and utilities improve transformer efficiency evaluation.

Sweep Frequency Response Analyzer (SFRA)

The Sweep Frequency Response Analyzer is an advanced diagnostic instrument used to detect mechanical deformation and internal displacement of transformer windings.

SFRA testing is commonly performed after:

• Short-circuit events
• Transportation
• Installation
• Major maintenance operations

By comparing frequency response characteristics, engineers can identify hidden winding abnormalities and evaluate transformer mechanical integrity.
