“…To verify the validity of our method, we first calculated, on paper, the output characteristics obtained by applying the proposed method and the conventional method for the resistive leakage current simulated waveform f(t) of a deteriorated ZnO element (as discussed in Section 2). 8 Comparison results when the fundamental waves are each set to 100% are shown in Figure 11. In the proposed method, we found that the harmonic components of the output voltage around the third to fifteenth orders, which are the subject of this paper, were continuously amplified, and that the amplitudes thereof were greater than those of the fundamental wave.…”

This paper presents a novel detection device for deteriorated zinc‐oxide (ZnO) surge arresters. It is necessary to understand the state of ZnO surge arresters for AC traction substations under operation. The waveform distortion of leakage currents can be detected through an increase in multiple harmonic currents; therefore, this effect was employed to develop a device for diagnosing damage to the surge arrester. By adopting a Rogowski coil and band‐pass filters, we can obtain more output of the 5th–15th order harmonic currents in comparison with conventional devices. If the threshold value of harmonic elements is exceeded, the lights on the device may light up to indicate the deterioration. The validity of the device was verified by artificial deterioration tests using damaged ZnO elements and a capacitor. This developed device could indicate the soundness of the surge arresters that are in proper working order while being under the influence of feeding voltages, which include harmonic voltages.

“…Lightning arrester failure is mainly caused by internal defects and external overvoltage. Several monitoring devices are developed for the arrester on‐line test [14–16]. Several methods exist in the surge protection industry for detecting and disconnecting the defective arresters [17–19].…”

The roof arrester of electric multiple units (EMU) can efficiently limit the overvoltage, and ensure the safe operation of the EMU electrical equipment. In the process of highspeed operation, the traction power supply system is often affected by overvoltage. In addition, roof arrester explosion accidents occasionally occur. In this paper, the on-line voltage measurement system of the EMU arrester is developed. By analysing a large number of voltage waveforms, the abnormal voltage is divided into three categories: over-phase voltage, high harmonic voltage and steep impulse overvoltage. The characteristics of abnormal voltage waveforms are then summarised. The electrothermal coupling simulation model of the arrester is developed, and the current response and temperature distribution of the arrester under abnormal voltage are calculated. The impact of the impulse voltage energy on the arrester temperature is studied by applying a triangular wave voltage to the model. Finally, some suggestions are proposed for the operation and maintenance of the roof arrester.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
