SDJ series capacitor current testerDetailed product description：

The SDJ series power grid capacitor current tester adopts the latest domestic technology, which does not require switching capacitors or dealing with the primary side. It only needs to measure from the PT secondary side, and the entire measurement process is convenient, safe, and accurate.

Main Features
① Easy to operate and safe. During testing, there is no need to work on the primary side of the distribution network, only signals are introduced through the PT opening triangle, thus avoiding the possibility of misoperation caused by contact with the primary circuit and the danger of explosion caused by external capacitors used for switching tests. The entire measurement work can be completed within one minute, which is very safe and convenient.
② No special safety measures are required. Due to the weak measurement signal injected from the PT opening triangle, it will not have any impact on the relay protection and PT itself. The output terminal of this tester can withstand an AC voltage of 100V. If there is a single-phase grounding fault in the system during measurement, it will not damage the PT and tester, so no special safety measures are required.
③ The instrument has a small volume, light weight, and is easy to carry.
④ Strong anti-interference ability. By using a different frequency test signal, the 50Hz power frequency interference signal is avoided, and the test results are accurate, stable, and reliable.
