摘　　要：根据超声波(AE)局部放电检测仪和暂态地电位(TEV)局部放电检测仪技术条件,结合现场需求,提出了用检测仪的线性度误差和稳定性误差表征局放检测仪性能的关键指标,并建立了专用性能测试平台,同时研究了2个厂家局放检测仪的测试性能。According to the technical conditions of acoustic emission （ AE） partial discharge （PD） detectors and transient earth voltage （TEV） partial discharge （PD） detector, and combined with the spot demand, a method that the key indicators of partial discharge detectors are represented by linearity error and stability error are proposed in the paper. The special performance test platform is established, and the test performance of partial discharge detectors from two different manufactories is studied.
