“…However, high-or low-voltage equipment co-existing in smart substations has led to the complexity of these substations' electromagnetic compatibility (EMC) [4]. The reliability of intelligent electronic equipment that is arranged next to high-voltage (HV) gas insulated switchgear (GIS) is greatly reduced [5], which has become one of the restrictions for the intelligent substations' development and application [6].…”

With the gradual increasing of the transmission voltage level, the situation of interference on secondary side equipment in smart substations is becoming more serious. The authors tested the interference waveforms caused by the circuit breaker's operation at the smart substation, which showed the severity of the electromagnetic (EM) environment. This paper takes the electronic current transformer acquisition card as an example. The influence of EM interference sources on the reliability of the acquisition card is analyzed. Then, standardized electromagnetic compatibility (EMC) immunity tests of the international electrotechnical commission (IEC) for different interferences are implemented. Typical output characteristics of acquisition cards for different tests are analyzed. Innovatively, this paper proposes a quantitative evaluation method of output waveform disturbance to evaluate the acquisition card's performance. This disturbance distortion is of great significance to the EM environment estimation of the acquisition card.
