Partial discharge pulse sequence analyses-a new representation of partial discharge data

Computer-based partial discharge (PD) data acquisition and analyses are common in use. Over the last two decades, there has been tremendous growth in PD data processing to extract information. There are efforts made to make data banks of different PD signature patterns based on φ-q-n measurements on insulation models. Problems related to standard PD measurements and quantification has resulted in ambiguous interpretations. This paper presents an alternative representation of PD data which includes the PD pulse time characteristics and its phase position. The representation is indicative of PD phenomenon and will be useful for PD diagnosis
