高压线路参数测试仪示值误差测量结果的不确定度评定

Uncertainty Evaluation for Indicated Value Error of High Voltage Transmission Line Parameter Tester

高压线路参数测试仪在电力系统中测量各种线路工频参数值,以作为计算系统短路电流、继电保护整定、推算潮流分布和选择合理运行方式等工作的实际依据。为了保证量值的可靠传递及满足认可实验室对检测结果的要求,文章就高压线路参数测试仪示值误差测量结果的不确定度进行了评定。

Parameter tester of high voltage transmission line measures power frequency parameter value of various lines in electric power system,it can be reference for calculating short circuit,relay protection setting,predicting load flow distribution and selecting reasonable operating mode.In order to ensure reliable value transfer,and meet the requirement of laboratory accreditation for testing result,the paper evaluates the indicated value error uncertainty of high voltage transmission line parameter tester.
