Unit Auxiliary Transformer Sample Clauses

Unit Auxiliary Transformer. The Facility shall include two factory tested unit auxiliary transformers as described below. The two individual unit auxiliary transformers shall supply power to station auxiliary loads and both shall be directly connected to the generator bus. Each transformer shall have a medium-voltage secondary. The transformer high-voltage windings shall be connected between the main transformer and the generator breaker through a tap in the generator bus, while the secondary windings shall be connected to the medium-voltage switchgear through either non-segregated phase bus (NSPB) or cable bus and a main breaker in the switchgear. Each transformer shall be mineral-oil-filled, outdoor type, with a no-load tap changer capable of operation from ground level, with visible indication of tap position, capable of padlocking. Tap changers shall be provided with two 2.5% taps above and below rated voltage. Transformers shall have standard accessories including but not limited to fault pressure relays, mechanical pressure relief devices, magnetic liquid level gauge with alarm contacts, top oil temperature indicator with alarm contacts, and winding temperature indicator with alarm contacts, and combustible gas device. Transformers shall be ONAN/ONAF/OFAF with the second stage of forced cooling to be for future load capability. The average winding temperature rise at full load capability of each stage shall be 65C over 40C ambient. The design shall provide two transformers so that the failure of one transformer will not shut down or limit the output of the station. Each transformer’s output will feed one bus so if a unit auxiliary transformer fails, its bus will be automatically picked up by the circuit breaker that connects the two busses. The unit auxiliary transformers shall be accordingly sized. Unit auxiliary transformer losses shall be minimized at full load operation. The oil inside the transformer tank shall be isolated from the atmosphere by means of an elevated expansion tank with an enclosed air cell.

  • Unbundled Voice Loops (UVL) may be provisioned using any type of facility that will support voice grade services. This may include loaded copper, non-loaded copper, digital loop carrier systems, fiber/copper combination (hybrid loop) or a combination of any of these facilities. BellSouth, in the normal course of maintaining, repairing, and configuring its network, may also change the facilities that are used to provide any given voice grade circuit. This change may occur at any time. In these situations, BellSouth will only ensure that the newly provided facility will support voice grade services. BellSouth will not guarantee that Southern Telecom will be able to continue to provide any advanced services over the new facility. BellSouth will offer UVL in two different service levels - Service Level One (SL1) and Service Level Two (SL2).

  • Power Factor Design Criteria (Reactive Power A wind generating plant shall maintain a power factor within the range of 0.95 leading to 0.95 lagging, measured at the Point of Interconnection as defined in this LGIA, if the ISO’s System Reliability Impact Study shows that such a requirement is necessary to ensure safety or reliability. The power factor range standards can be met using, for example without limitation, power electronics designed to supply this level of reactive capability (taking into account any limitations due to voltage level, real power output, etc.) or fixed and switched capacitors if agreed to by the Connecting Transmission Owner for the Transmission District to which the wind generating plant will be interconnected, or a combination of the two. The Developer shall not disable power factor equipment while the wind plant is in operation. Wind plants shall also be able to provide sufficient dynamic voltage support in lieu of the power system stabilizer and automatic voltage regulation at the generator excitation system if the System Reliability Impact Study shows this to be required for system safety or reliability.
