April 23th, 2012, PONOVO was invited by Shannxi Electric Power Research Institute to detect the partial discharge in Baoji substation. For two days’ testing, the engineers detected the convertor pole phase 1B by Pocket-AE tester. There was partial discharge signal in phase A, B, C of 750kV reactor. The test results were similar to the detection results tested by engineers from Shannxi EPRI. PONOVO completed the detection successfully and won great recognition of the local EPRI.
The detection proves the Pocket-AE tester with great immunity to electromagnetic interference, and accurate fault location ability. The equipment owns simple humane signal display interface and light-weight. The features make it surpass the similar product.
