Drafting is required. This document replaces GB/T 25738-2010 "Technical Guidelines for Commissioning of Electric Motors in Nuclear Power Plants". In addition to structural adjustments and editorial changes, the main technical changes are as follows. The scope of application has been changed (see Chapter 1, Chapter 1 of the.2010 edition); a) The definition of nuclear safety-grade motor has been changed (see 3.2, 3.2 of the.2010 edition); b) Added the requirements for the completion of motor installation (see 4.1.3); c) The provisions for checking lubricating oil have been changed [see 4.2.2 e) and 4.2.2 e) of the.2010 edition]; d) Added the requirement to check the current transformer (CT) wiring [see 4.4.1 g)]; e) Added the requirement to check the neutral point connection [see 4.4.1 h)]; f) Added the requirement to inspect the inverter [see 4.4.1 k)]; g) Added requirements for no-load starting voltage drop measurement (see 4.4.3.1); h) Added requirements for no-load starting of motors with frequency converters (see 4.4.3.7); i) Added requirements for measuring the voltage drop when starting with load (see 4.4.4.2); j) Change “low-voltage motor” to “motor with rated voltage below 1 000 V” and change “high-voltage motor” to “motor with rated voltage below 1 000 V”. Motors with a voltage of 1 000 V and above" (see 4.4.3.2, 4.4.4.3, 4.4.4.4,.2010 edition 4.4.3.2, 4.4.4.3, 4.4.4.4); k) The normative appendix "Quality Appraisal and Special Tests for Typical Nuclear Safety-Grade Motors" (see Appendix A of the.2010 edition) has been deleted.
