Resumo: | |||||||||||||
Impulse testing for puncture insulator is a standardized test described in IEC 61211:2004 and is essential for laboratory testing of the quality of glass or porcelain insulators used in the electrical power system. IEC 60060-2:2010 recommends that calibration of Measurement Systems used in Impulse Puncture Test on insulators (IPMS) should be performed by comparison against a standard. However, although the impulse puncture testing is standardized, there are still no standards for traceability of this measurement system at most research institutes globally. Quantifying the amplitude of an impulse puncture test, with all metrological guarantees, is not a trivial task, since it is an impulsive signal with amplitude of hundreds of kilovolts and durations of the order of 200 ns. In addition, high dynamic performance voltage dividers for this specific application are not commercially available either. Thus, the objective of this dissertation was
to design and develop an IPMS. The voltage divider, which is part of the measuring system, is designed to ensure minimum inductance and high dynamic performance. A filter for electromagnetic interference removal based on the wavelet transform was also developed, integrated with software that controls acquisition, signal conditioning, determination and analysis of the impulse puncture testing parameters. The performance of the measuring system was evaluated at low voltage and high voltage, as well as its measurement uncertainty was estimated, being able to meet the normative and metrological requirements of the Cepel s Measurement Reference Laboratory.
