On-line Monitoring and Acquisition System Based on DSP+CPLD Mode for Electrical Apparatus of Substation

Condition monitoring of electrical apparatus in substation is an important work for the reliable performance of electrical devices. A new on-line condition monitoring approach and technique is presented, which is developed by DSP+CPLD mode. In this paper, as an example, we introduce the monitoring and acquisition system based on DSP+CPLD mode which used for circuit breaker condition assessment. The syetem's hardware configuration, working principle and advantages are discussed. As a result, with the performance of high speed, high integration and high reliability, the on-line monitoring technique based on DSP+CPLD mode will play a very important role in the field of electrical apparatus condition monitoring.
