Complexities of the power system with its own unlimited influencing factors, combined with the type and quality of operational practices can lead to situations of unwanted and unexplained operation of a protection system. Analysing every such incident by identifying the cause is vital in preventing such incidents from recurring. Such an analysis also provides valuable insights into various aspects of the primary and secondary systems, contributing to its improvement. Performing this analysis requires a very high level of power system and protection application knowledge, hands-on field experience, along with an analytical troubleshooting approach.
Site problem investigation:
Our in-depth knowledge and vast experience puts us at a very good advantage to perform on-site investigations into the unwanted operations of the protection system. We perform a thorough investigation into the incident, analysing the available post fault data to identify the cause of the incident. We also provide valuable inputs to improve the performance and to avoid repetition of such incidents. Advice on installing fault recording/analysing devices and improving operating practices are also provided.
Protection system restoration:
Often, repeated nuisance operation of a protection system leads to it being kept out of service. This could be due to the unsuccessful earlier attempts to identify the causes and rectify them. The reasons could be many, such as failure of protection device, incorrect setting, wrong wiring and improper operating practice. With our experience we can investigate into such installations, identifying the cause and provide assistance in restoring the protection system and putting it back into service. This results in the customers getting complete returns for their investment.
