Transformer Testing

Testing power transformers is essential to ensure their reliability, efficiency, and longevity. Various tests can be performed to assess the transformer's condition and performance. Here are some common types of testing:

1. Insulation Resistance Testing: This test measures the insulation resistance of the transformer windings to detect deterioration or moisture in the insulation, which can lead to failures.

2. Dielectric Testing: Includes tests like the Power Factor Test and the Dissipation Factor Test, which evaluate the insulation's dielectric properties to identify aging or contamination.

3. Turns Ratio Testing: This test checks the turns ratio between the primary and secondary windings to ensure the transformer is providing the correct voltage transformation and is not damaged.

4. Excitation Current Testing: Measures the current required to energize the transformer's core, helping to identify issues such as shorted turns or core defects

Breaker Testing and Maintenance

Travel and timing tests on circuit breakers are essential to ensure their proper operation and reliability. These tests verify that breakers open and close within specified time and travel limits, crucial for responding quickly to electrical faults and protecting the system. By assessing the physical movement and operational speed, these tests identify wear, misalignment, or obstructions in the mechanical components. Regular testing allows for predictive maintenance, helping to detect early signs of degradation and reducing the risk of unexpected failures. Ultimately, these tests ensure the safety and efficiency of electrical systems.

Thermal Imaging and Partial Discharge

Infrared cameras are used to detect hotspots and uneven temperature distribution, indicating potential issues such as overloading or poor connection. We also use a partial discharge camera which uses microphones to detect partial discharge caused by defects in the insulation, degradation of insulation, contaminants and moisture, and electric stress, improper installation or assembly, aging equipment. Partial discharge can lead to further degradation of insulation material, eventually causing equipment failure, if not detected and addressed in a timely manner. Regular monitoring and maintenance are crucial to managing partial discharge risks in electrical systems.
