Transformer Testing and Maintenance Services
In many industrial facilities, transformers are installed to meet high demand for energy. These transformers are designed with the power and specifications necessary to meet the energy needs of businesses. Over time, the internal requirements and capacity of businesses may change. Additionally, transformers require regular maintenance and inspections based on their type and characteristics.
The Regulation on Health and Safety Conditions in the Use of Work Equipment mandates that transformers must be periodically inspected by qualified engineers.
As mentioned, transformers are crucial as our energy source. In the event of a transformer failure, the business will experience an energy outage, putting production continuity at risk. More importantly, if transformer failures are not addressed by specialized teams, high voltage-related risks will persist.
Transformer Winding Insulation Resistance Tests
Winding resistance measurements are performed to check for any insulation issues between the primary and secondary windings that could lead to faults.
Transformer Turn Ratio Tests
Turn ratio tests assess whether there is an error between the primary and secondary voltages, helping us determine if the transformer is functioning correctly within the desired voltage range. Transformer turn ratios are measured by changing transformer taps.
Transformer Insulation Tests
Insulation tests detect any insulation faults between High Voltage-Low Voltage-transformer tank. Potential insulation faults are evaluated.
Transformer Thermal Imaging and Reporting
Thermographic inspections are conducted to monitor the temperature of transformers, and images are recorded. These images are analyzed using a thermal camera analysis program and presented to the customer in a report.
Protection and Operational Grounding Measurements
Operational protection groundings of transformers are measured using a three-point measurement method to ensure they meet the calculated threshold values.
Circuit Breaker Contact Resistance Measurement
The contact resistances of circuit breakers in cells are measured with professional devices to check for compliance.
Protection Relay Function Tests
Protection relays are crucial for preventing significant electrical outages and workplace accidents in case of faults. Regular testing of protection relays with professional equipment and specialized engineers is essential.
Current and Voltage Transformer Turn Ratio Tests
Current and voltage transformers are used for measurement and protection purposes. Errors in the turn ratios of these transformers can lead to inaccuracies in reading values and fault currents affecting protection relays. To prevent such errors, the turn ratios of current and voltage transformers must also be tested.
Transformer Maintenance and Cleaning Services
Regular maintenance and cleaning of transformers can help prevent potential faults.
