Primary Equipment Testing: Our skilled technicians conduct a range of primary equipment tests to assess the performance and condition of critical components in your substation. We perform insulation resistance tests, power factor testing, contact resistance tests, and transformer testing to ensure that transformers, circuit breakers, switches, and other primary equipment are operating within specified parameters. Through these tests, we identify any abnormalities, deteriorations, or potential failures that could impact the overall system performance.

Protection System Testing: The protection system is crucial for ensuring the safety and reliability of your substation. We conduct comprehensive testing of protection relays, protective device coordination, and scheme verification to ensure the accurate and reliable operation of the protection system. Our testing includes primary injection testing, secondary injection testing, relay coordination testing, and fault analysis. By thoroughly evaluating the protection system, we help you mitigate the risk of equipment damage, personnel injury, and service interruptions.


Relay Coordination Study:

A well-executed relay coordination study is essential to protect your electrical system from faults and ensure efficient and selective operation. Our engineers conduct comprehensive relay coordination studies, taking into account system characteristics, equipment ratings, protective device settings, and coordination requirements. Using advanced software and industry-standard techniques, we analyze fault scenarios and determine the appropriate relay settings and coordination curves for each protective device, optimizing system reliability and minimizing downtime.

Testing and Verification: To validate the accuracy and effectiveness of relay settings determined during the coordination study, we perform rigorous testing and verification. Our skilled technicians conduct primary and secondary injection testing to simulate fault conditions and measure the response of protective relays. This process ensures that the relays operate correctly and in coordination with one another, providing reliable protection against overcurrent, undervoltage, overvoltage, and other fault conditions.
