Purpose The purpose of this standard is to cover conformance test requirements for current and inductively coupled voltage transformers used for measurements and control fu
22、nctions on 60 Hz primary systems with voltages from 600 V through 38 kV. This standard does not specifically cover the following: Installation in ships, watercraft, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles Installations underground in
23、mines Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock, or installations used exclusively for signaling and communication purposes Installations of communication equipment under the exclusive control of c
24、ommunication utilities, located outdoors or in building spaces used exclusively for such installations Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the lat
25、est edition of the referenced document (including any amendments or corrigenda) applies. 1 Copyright 2005 IEEE. All rights reserved.

ANSI/UL 1446, Standard for Systems of Insulating MaterialsGeneral.33.4.5.Definitions For the purposes of this standard, the following terms and definitions apply. The Authoritative Dictionary of IEEE Standard
27、s Terms B1,4as well as IEEE Std C57.12.805, should be referenced for terms not defined in this clause. 3.1 conformance tests: Certain performance tests used to demonstrate compliance with the applicable standards. The test specimen is normally subjected to all planned routine tests prior to initiati
28、on of the conformance test program. NOTEThe conformance tests may, or may not, be similar to certain design tests. Demonstration of margin (capabilities beyond the standard) is not required.6Selection of the transformer for conformance testing Representative samples shall be chosen jointly by the co
29、ncerned parties and shall represent the typical commercial product of the manufacturer. Five current or voltage transformers shall be tested, except for the case of unusual or infrequently used types in which a smaller number that is acceptable to the certifying agency may be taken to be representat
30、ive of the type. (The certifying agency may be the manufacturer.) The sample shall be selected as to be representative of the range of ratios to be certified as conforming. Basis for conformance A transformer type shall be in conformance with the standards listed when each current or voltage transfo
31、rmer withstands all insulation tests specified in 7.1 and 7.2, meets the requirements for both accuracy and temperature rise tests specified in 7.3 and 7.4, and meets the requirements for mechanical rating tests specified in 7.5. The failure of a transformer to meet the requirements of the accuracy,
32、 temperature-rise, or mechanical rating tests shall be cause to reject that rating and other ratings represented by the sample. Such rejection shall not preclude the conformance of the type in other ratings that have different design characteristics and that do meet all test requirements. 1IEEE publ

36、2.1a) b) c) d) Treatment of failures within test sequence Failures occurring during conformance testing should be evaluated, and corrections should be made before any re-testing is carried out. A design change made to a transformer to correct a failure within a test sequence shall be evaluated for i
37、ts effect on any preceding sequence. Tests Conformance tests shall consist of the following tests performed in the sequence shown on each transformer selected for tests. Impulse tests Impulse tests shall be made as specified in 8.8.5 of IEEE Std C57.13 and at the test levels indicated for the transf
38、ormer BIL in Table 2 of IEEE Std C57.13-1993. Voltage withstand tests Voltage withstand tests of primary windings to grounded secondary windings and parts, including metallic case, frame, base, nameplate, mounting facilities, and the core (if accessible), shall be made as specified in 8.8.3 of IEEE
39、Std C57.13-1993 and the values indicated in Table 2 of IEEE Std C57.13-1993. Accuracy Metering accuracy of current transformers Metering accuracy test shall be made per 8.1 of IEEE Std C57.13-1993. The transformers shall be demagnetized and then tested at 10% and 100% of rated primary current and wi
40、th a primary current equal to the rated current multiplied by the continuous thermal current rating factor. Tests shall be made with the minimum and maximum standard metering burdens for which the manufacturer assigns the same metering accuracy class. In the case of dual ratio and multi-ratio transf
41、ormers, tests shall be made to verify the accuracy at all ratios assigned accuracy ratings by the manufacturer and to verify the ratio of each tap. Relaying accuracy of current transformers Relay accuracy classes assigned by the manufacturer shall be verified in 7.3.2.1 and 7.3.2.2. Transformers ass
42、igned “C” classification Check ratio per 8.1 of IEEE Std C57.13-1993. Measure resistance of the secondary winding. Test excitation current per 8.3.2 of IEEE Std C57.13-1993. Using data from (b) and (c), calculate relay accuracy per 8.1.10 of IEEE Std C57.13-1993 to verify that the transformers meets

IEEE Std C57.13.2-2005 IEEE Standard Conformance Test Procedure for Instrument Transformers 7.3.2.27.3.37.47.4.17.4.27.5Transformers assigned “T” classification These transformers shall be tested per 8.1 of
44、 IEEE Std C57.13-1993 to verify that the relay accuracy requirements of 6.4 of IEEE Std C57.13-1993 are met. Accuracy of voltage transformers The transformers shall be tested at 90% and 100% of rated voltage with zero burden and at 110% of rated voltage at the maximum burden for which an accuracy cl
45、ass is assigned by the manufacturer. Accuracy at other burdens may be determined by test or by calculation, as specified in 8.1.12 of IEEE Std C57.13-1993. The accuracy at 90% and 110% of the rated voltage at any burden may be determined by applying the ratio and phase angle differentials determined
46、 in the zero burden test to the accuracy for that burden at 100% of rated voltage. Temperature rise Temperature risecurrent transformers Each transformer shall be tested with a primary current equal to the rated current multiplied by the continuous thermal current rating factor. The temperature rise
47、 tests shall be made in accordance with 8.7 of IEEE Std C57.13-1993, and the temperature rise for continuous operation shall not exceed the limits in Table 4 of IEEE Std C57.13-1993. In case of a dual ratio or multi-ratio transformer, the temperature tests should be made at the primary rating that p
48、roduces the greatest temperature rise. Temperature risevoltage transformers Each voltage transformer shall be tested with 100% of rated primary voltage at the thermal burden rating assigned by the manufacturer. The temperature rise tests shall be made in accordance with 8.7 of IEEE Std C57.13-1993 a
49、nd the temperature rise for continuous operation shall not exceed the limits specified in Table 4 of IEEE Std C57.13-1993. In the case of a dual ratio or multi-ratio transformer, the temperature tests should be made at the primary rating that produces the greatest temperature rise. Mechanical rating test The test to demonstrate the short-time mechanical current rating of a wound current transformer (excluding window and bar type) shall be made by subjecting the current transformer, with secondary winding short-circuited, to at least one peak of a prim
