29、s use may become mandatory only when required by a duly constituted legal authority or when specified in a contractual relationship. To meet specialized needs and to allow innovation, specific changes are permissible when mutually determined by the user and the producer, provided that such changes d

NOTEThe editing instructions contained in this corrigendum define how to merge the material contained t
35、herein into the existing base standard and its amendments to form the comprehensive standard. The editing instructions are shown in bold italic. Four editing instructions are used: change, delete, insert, and replace. Change is used to make corrections in existing text or tables. The editing instruc
36、tion specifies the location of the change and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new material). Delete removes existing material. Insert adds new material without disturbing the existing material. Insertions may require renumbering.
37、 If so, renumbering instructions are given in the editing instruction. Replace is used to make changes in figures or equations by removing the existing figure or equation and replacing it with a new one. Editing instructions, change markings, and this NOTE will not be carried over into future editio
38、ns because the changes will be incorporated into the base standard.

39、llows: 5.1.9 Sudden pressure relay When specified, a sudden pressure relay shall be provided for the indication of transformer faults, and to minimize damage to equipment. The relay shall not actuate under normal transformer operating pressures. The sudden pressure relay may be either a sudden-oil-p
40、ressure relay, mounted on the tank below the lowest liquid level, or a sudden-gas-pressure relay, mounted in the region of the gas space. gas space mounted relay or a under fluid relay. Under fluid relays The sudden-oil pressure relay shall actuate under rapidly changing pressures of 10 kPa/s to 38
41、kPa/s (1.5 lb/in/s to 5.5 lb/in/s). The gas space mounted relays The sudden-gas-pressure relay shall actuate with a pressure change of 3.5 kPa/s to 21 kPa/s (0.5 lb/in/s to 3.0 lb/in/s). The sudden pressure relay seal-in circuit shall actuate within 3 cycles of the rated power frequency, after the pressure relay operation. The sudden pressure relay shall be able to withstand full vacuum or positive pressure of 103 kPa (15 lb/in) without damage. The relay seal-in circuit shall as a minimum be supplied with an alarm contact and a trip contact in accordance with 5.1.10 and 5.1.11.
