The pacing system malfunction can be detected by analyzing pacing ECG and the pacing systemimpedance.
将起搏系统阻抗和起搏心电图联系起来分析，有助于判断起搏系统故障的原因。

Adaptive protection device USES local information only and can only adapt to changes of systemimpedance of less area of power system.
保护装置自适应由于只利用本地信息，只能适应较小范围的系统运行方式变化。

However, due to large systemimpedance of ITER testing platform, the requirement of reducing transformer impedance is commonly met in actual transformer industry.
