This paper dealt with the application of transient earth voltage (TEV) sensors for the online measurement and analysis ofpartial discharge (PD) in medium-voltage switchboards. To simulate the typical insulation defects in the switchboards, fourtypes of artifi cial electrode systems, including high-voltage protrusion, low-voltage protrusion, particle-on-conductor, andvoid inside cast-resin potential transformer were fabricated. A TEV sensor with a frequency range of 1?150 MHz and anon-inductive resistor were used to detect the PD-induced TEV signal and the PD voltage pulse, respectively. The frequencyspectrums of TEV signals were analyzed, and it was found that they had a mutual frequency range of 5?50 MHz. However,the amplitude of TEV signal was not proportional to the apparent charge specifi ed in IEC 60270, resulting the diffi culty ofquantifi cation of PD. The phase-resolved partial discharge patterns were acquired using the TEV sensor and the developedmeasuring algorithm, by which distinguishable patterns were obtained from diff erent defects.
