Voltage Transformer (GIS Sample Clauses

Voltage Transformer (GIS. The Voltage Transformers shall conform to IEC-61869. The Voltage Transformers shall be of electromagnetic type with SF6 gas insulation. The earth end of the high voltage winding and the ends of the secondary winding shall be brought out in the terminal box. The Voltage Transformers shall be located as a separate bay module and will be connected phase to ground and shall be used for protection, metering and synchronization. The Voltage Transformers shall be of inductive type, nonresistant and shall be contained in their own- SF6 compartment, separated from other parts of the installation. The Voltage Transformer shall be effectively shielded against high frequency electromagnetic transients. The Voltage Transformer shall have three secondary windings out of which two shall be used for protection and one for metering. The Voltage Transformer should be thermally and dielectrically safe when the secondary terminals are loaded with the guaranteed thermal burdens. The accuracy class for protection cores shall be 3P. The accuracy of 0.2 on metering core should be maintained throughout the entire burden range on all the three windings without any adjustments during operation. The rated burden of cores shall be closer to the maximum burden requirement of the metering and protection system (not more than 50 VA for metering core) for better sensitivity and accuracy.

  • TRENCH SHORING If this Contract is in excess of $25,000 and is for the excavation of any trench deeper than five (5) feet, Contractor must submit and obtain District’s approval and acceptance, in advance of excavation, of a detailed plan showing the design of shoring, bracing, sloping, or other provisions to be made for worker protection from the hazard of caving ground during the excavation of such trench or trenches. If the plan varies from the shoring system standards, the plan shall be prepared by a registered civil or structural engineer.

  • Tandem Switched Transport 7.3.4.2.1 For traffic delivered through a Qwest or CLEC tandem Switch (as defined in the Agreement), the Parties agree that, because this State is a new market for CLEC, tandem switched transport functions for Exchange Service (EAS/Local) non-transit traffic shall be compensated based upon the xxxx and keep compensation mechanism. Xxxx and keep will apply to both the tandem switching rate and the tandem transmission rate. Xxxx and keep shall govern compensation for such traffic exchanged by the Parties in this State until the earlier of: (1) the expiration of the Agreement, or (2) further action by the Federal Communications Commission (FCC), or a court of competent jurisdiction, vacates, replaces, modifies, or supersedes the applicable rules adopted in Order on Remand and Report and Order, CC Docket Nos. 96-98, 00-00, XXX 00-000 (xxx. Apr. 27, 2001). 7.3.4.2.2 Intentionally Left Blank.
