Reliability verification of system applying a microprocessor in a high-voltage gas insulated substation

摘要

Relating to the microprocessor control and monitoring system applied in a GIS (gas insulated substation), this paper describes a series of reliability evaluation tests carried out during its development, and evaluation results on the basis of field data. According to the test results, it was found that the system developed has greater reliability for practical application from the viewpoint of EMC and life. In addition, a cost evaluation of the system developed was also carried out to compare the costs of a conventional system, thus verifying the economical advantages of the system developed.
