Introduction This introduction is not part of IEEE Std C57.113-2010, IEEE Recommended Practice for Partial Discharge Measurement in Liquid-Filled Power Transformers and Shunt Reactors. The detection of partial discharges (PDs)
6、 was introduced for quality assurance tests of high-voltage (HV) apparatus at the beginning of 1960. Originally this technique was based on the measurement of radio interference voltages (RIV) in terms of microvolts (V) as recommended by NEMA TR1-1974 B112, NEMA 107-1964 B113, and CISPR 16-1-1993 B4
7、2.aThis quantity, however, is weighted according to the acoustical noise impression of the human ear, which is not a measure of the PD activity in the insulation of HV apparatus. As a consequence, Technical Committee No. 42 of IEC decided to prepare a separate standard for PD measurements associated
8、 with the apparent charge, which was first published in 1968. Since that time, this technology is considered as an indispensable tool for an enhancement of the reliability of HV apparatus. IEEE Std C57.113-2010 covers the wideband method for apparent charge measurements in compliance with the third

Overview 1.1 Scope This recommended practice describes the test procedure for the detection and measurement by the wideband apparent charge method of partial discharges (PDs) occurring in liquid-filled power transformers and shunt reactors during dielectric
39、 tests, where applicable. 1.2 Purpose PD measurements in transformers and shunt reactors should preferably be made on the basis of measurement of the apparent charge. Relevant measuring systems are classified as narrowband or wideband systems. Both systems are recognized and widely used. Without giv
40、ing preference to one or the other, it is the object of this document to describe the wideband method. General principles of PD measurements, including the narrowband method, are covered in IEC 60270 and IEC 60076-3 B71.1,21Information on references can be found in Clause 2. 2The numbers in brackets

Definitions For the purposes of this document, the following terms and definitions apply. The IEEE Stan
45、dards Dictionary: Glossary of Terms see Annex A. If the bushing tap coupling mode according to Figure 1 is used, the measuring impedance, Zm, consists of the parallel connection of a resistor, Rm, and an inductor, Lm. Both elements are additionally shunted by the capacitance between bushing tap and
46、grounded bushing flange, C2; see Annex A. Moreover, passive and active elements could be utilized for PD signal filtering and overvoltage protection. All these elements are usually integrated in a terminating box, referred to in IEC 60270 as a coupling device, Dc. Due to the high-pass filter charact
47、eristics of the series connection of either Ckor C1with the measuring impedance, Zm, care should be taken that the specified lower limit frequency, f1, of the complete PD measuring circuit is not substantially affected by the parameters of the PD coupling unit; see Annex A. WARNING In order to minim
48、ize any danger for the operator and the instrumentation, as well as to ensure an optimum signal transmission, the coupling device should always be located inside the HV test area. The coupling device shall be attached physically as close as possible to the bushing tap or to the coupling capacitor. 4
49、.4 PD measuring instrument For measuring the apparent charge, either the analog or the digital signal processing can be utilized. Independent from the measuring principle applied, the instrumentation is generally equipped with the following major units: Attenuator, to adjust the magnitude of the input PD pulses Band-pass filter amplifier, to amplify and integrate the captured PD pulses Peak detector, to evaluate the apparent charge level To ensure comparable and reproducible PD test results, both the frequency response and the pulse train response of PD m
