DIN 42600-7:2013-10

The DIN 42600 series "Instrument transformers for 50 Hz, U_m 0,72 kV to 52 kV" is applicable for the designs and dimensions of instrument transformers for air-insulated indoor installations with maximum equipment voltage from 0,72 kV to 52 kV and consists of the following parts: - Part 1: Basic requirements - Part 2: Current transformers U_m = 0,72 kV and U_m = 1,2 kV - Main dimensions - Part 3: Voltage transformers U_m 12 kV to 36 kV - Large design, main dimensions, indoor type - Part 4: Current Transformers (support-type-insulator) U_m = 12 kV - Small design, main dimensions, indoor type - Part 5: Current Transformers (support-type-insulator) U_m 12 kV to 36 kV - Large design, main dimensions, indoor type - Part 7: Voltage Transformers U_m to 12 kV - Small design, main dimensions, indoor type - Part 8: Current Transformers (support-type-insulators) U_m = 12 kV and U_m = 24 kV - Narrow design, main dimensions, indoor type - Part 9: Voltage Transformers U_m = 12 kV and U_m = 24 kV - Narrow design, main dimensions, indoor type. This standard is applicable for instrument transformers for air-insulated indoor installations with maximum equipment voltage from 0,72 kV to 52 kV. Instrument transformers for U_m = 3,6 kV and U_m = 7,2 kV are preferably manufactured for the design for U_m = 12 kV. For instrument transformers U_m = 52 kV there exist no special specifications for the design; for this purpose only the general statements of this standard apply. It shall be applied analogously for transformers for metal-enclosed installations as well as for transformers for outdoor installations of the same voltage levels, provided no other specifications have been made. Part 2: Current transformers U_m = 0,72 kV and U_m = 1,2 kV - Main dimensions This standard is applicable for current transformers for air-insulated indoor installations with maximum equipment voltage 0,72 kV to 1,2 kV. This standard shall be used in conjunction with DIN 42600-1. Part 3: Voltage transformers U_m 12 kV to 36 kV - Large design, main dimensions, indoor type This standard is applicable for voltage transformers for air-insulated indoor installations with maximum equipment voltage from 12 kV to 36 kV - Large design. This standard shall be used in conjunction with DIN 42600-1. Part 4: Current Transformers (support-type-insulator) U_m = 12 kV - Small design, main dimensions, indoor type This standard is applicable for current transformers for air-insulated indoor installations with maximum equipment voltage 12 kV - Small design. This standard shall be used in conjunction with DIN 42600-1. Part 5: Current Transformers (support-type-insulator) U_m 12 kV to 36 kV - Large design, main dimensions, indoor type This standard is applicable for current transformers for air-insulated indoor installations with maximum equipment voltage 12 kV to 36 kV - Large design. This standard shall be used in conjunction with DIN 42600-1. Part 7: Voltage Transformers U_m to 12 kV - Small design, main dimensions, indoor type This standard is applicable for voltage transformers for air-insulated indoor installations with maximum equipment voltage 12 kV - Narrow design. This standard shall be used in conjunction with DIN 42600-1. Part 8: Current Transformers (support-type-insulators) U_m = 12 kV and U_m = 24 kV - Narrow design, main dimensions, indoor type This standard is applicable for current transformers for air-insulated indoor installations with maximum equipment voltage from 12 kV to 24 kV - Narrow design. This standard shall be used in conjunction with DIN 42600-1. Part 9: Voltage Transformers U_m = 12 kV and U_m = 24 kV - Narrow design, main dimensions, indoor type This standard is applicable for voltage transformers for air-insulated indoor installations with maximum equipment voltage from 12 kV to 24 kV - Narrow design.
