The Application of New Diagnostic Protocols For The Condition-Based Assessment of High-Voltage Electrical Equipment

摘要

The diagnostic testing of insulation systems provides data that can be used to quantify the condition of high-voltage electrical equipment such as tap changers, circuit breakers, regulators and transformers. Using recently developed algorithms, condition codes for these types of equipment are generated using laboratory and field data. These codes are used to determine when maintenance is necessary and to establish priorities for maintenance. This paper describes how these condition codes are applied within condition-based maintenance programs. Case studies are included that illustrate the reliability and the fiscal impact of the protocols.
