Portable and Easy to Operate
Modern Tan Delta testers are compact, lightweight, and equipped with user-friendly interfaces for field and laboratory use. They can perform measurements at a wide range of voltage levels and under a wide range of environmental conditions.

Applications of Tan Delta Tester

Transformer Insulation Assessment: Tan delta tester is primarily used to evaluate the condition of transformer insulation, identifying potential insulation weaknesses or defects.

Diagnostic Testing: By comparing tan delta values over time, it is possible to detect gradual insulation deterioration and schedule timely maintenance or repairs.

Quality Control: Tan delta testing is performed during transformer manufacturing to ensure the quality and integrity of the insulation system.

Electrical Maintenance: Whether for routine checks or during the commissioning of new equipment, tan delta tester is essential for ensuring the continued safe operation of high-voltage systems.

Structure

Power Supply Unit: Generates the required test voltage for insulation measurement.

Capacitor: Provides a reference for accurate loss angle measurement and calibration.

Connection Terminal: The interface where the insulation sample or equipment is connected.

Voltage Sensors: Detect and transmit electrical signals for analysis.

Display Module: Includes the user interface, touchscreen or buttons, and display for results.

Safety System: Ensures safe operation with grounding, overvoltage, and interlock protections.

Safety Measures During Testing

Safety is critical during tan delta testing. Follow these guidelines to protect yourself and the equipment:

Wear Protective Gear

Use insulated gloves and safety goggles to prevent electrical injuries.

Ensure Proper Grounding

Verify that the equipment is properly grounded to avoid electrical shocks.

Monitor Voltage Levels

Keep an eye on the applied voltage to prevent overloading the insulation.

Maintain a Safe Distance

Stand away from the equipment during testing to minimize exposure to potential hazards.

Test Environment

Conduct the test in a controlled environment to minimize external factors that may affect the results, such as humidity or temperature.

Q: What about the transportation?

A: Usually we take door to door express delivery ,cause it's more convenient and fast.

Q: What is a Tan Delta Tester?

A: A Tan Delta Tester, also known as a dissipation factor or dielectric loss tester, is an instrument used to measure the insulation quality of electrical equipment such as transformers, cables, bushings, and generators. It determines the tangent of the dielectric loss angle (tan δ), which indicates how much energy is lost as heat in the insulation material.

Q: What does “Tan Delta” mean in electrical testing?

A: “Tan Delta” (tan δ) is the ratio of the resistive current (loss component) to the capacitive current (charging component) in an insulating material. A higher tan δ value means greater dielectric losses and poorer insulation quality.

Q: How often should you perform Tan Delta tester?

A: You should test critical equipment annually. For less critical systems, testing every two to three years is sufficient. Adjust the frequency based on environmental conditions and equipment usage.

Q: What equipment can you test using Tan Delta testers?

A: Tan Delta testers work on transformers, cables, bushings, and generators. Some kits are versatile, while others are tailored for specific applications like substations.

Q: How do you interpret Tan Delta values?

A: Compare test results to industry standards or baseline values. Normal readings indicate healthy insulation. Abnormal values suggest issues like moisture or contamination that require corrective action.

Q: Can the Tan Delta tester be used for oil-filled equipment?

A: Yes, the Tan Delta test is commonly used for assessing the insulation condition of oil-filled transformers and bushings, where it helps identify issues like moisture or contamination in the oil.

Q: What is the principle behind Tan Delta measurement?

A: The Tan Delta Tester applies an AC voltage to the insulation and measures both the current through the specimen and the phase angle between voltage and current. The tangent of the phase angle difference between the total current and the ideal capacitive current gives the tan δ value.
