一种测量继电保护测试仪采样值额定延时的方法及系统
摘要：
本发明提供一种测量继电保护测试仪采样值额定延时的方法及系统，所述方法包括：测量继电保护测试仪发送采样值SV报文时的同步误差；测量所述继电保护测试仪发送SV报文时的第一延时；报文分析仪根据所述的同步误差对所述的第一延时进行校准，得到所述继电保护测试仪的SV额定延时。通过在测试过程中首先测定继电保护测试仪发送采样值SV报文时的同步误差以及第一延时，进而根据同步误差对第一延时进行校准，最终得到精确的继电保护测试仪的SV额定延时。
摘要（英）：

The invention provides a method and system for measuring the SV rated time delay of a relay protection tester. The method comprises that a synchronous error when the relay protection tester sends an SV message is measured; first time delay when the relay protection tester sends the SV message is measured; and a message analyzer calibrates the first time delay according to the synchronous error, and the SV rated time relay of the relay protection tester is obtained. In the testing process, the synchronous error and the first time delay when the relay protection tester sends the SV message, the first time delay is calibrated according to the synchronous error, and the accurate SV rated time delay of the relay protection tester is obtained.
