Unit Auxiliary Transformer Sample Clauses

Unit Auxiliary Transformer. The Facility shall include two (2) 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) 2-1/2% 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. Temperature rise at full load capability of each stage shall be 65C average winding temperature rise over 40C ambient. The design shall provide two transformers so that the failure of one transformer will not shutdown 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 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.

  • HEATING, VENTILATING AND AIR CONDITIONING General Office Area: The building shall be equipped with a combination heating, ventilation and air conditioning system. The system shall have ducted supply and return air. The space above the ceiling shall not be used as a supply or return plenum. The systems shall be sized in accordance with the weather conditions identified in Chapter 13, “Energy Conservation” of the 1996 BOCA Building Code and supplemented by the “Building Code Rules”. All HVAC equipment shall be commercial or light industrial grade. If new construction it shall be installed at grade or within mechanical rooms for easy access and maintenance. If existing construction, roof mounted equipment will be considered after all other options have been exhausted, including the elimination of noise and vibration transfer to the structural members. The HVAC systems shall be zoned, with units sized and placed as required by heating and cooling loads on the building. Zoning of systems is dependent on the size, shape and orientation of the building. The HVAC system shall be divided into a minimum of 4 exterior and 1 interior temperature control zones. Return air shall be taken from the area supplied or adjacent to the area in the same temperature control zone. The ventilation and exhaust system shall be sized to maintain a positive pressure throughout the building envelope to limit air and dust infiltration. No HVAC ductwork shall be installed under the floor slab or underground.

  • ADJACENT EXCAVATION-SHORING 32. If an excavation shall be made upon land adjacent to the demised premises, or shall be authorized to be made, Tenant shall afford to the person causing or authorized to cause such excavation, license to enter upon the demised premises for the purpose of doing such work as said person shall deem necessary to preserve the wall or the building of which demised premises form a part from injury or damage and to support the same by proper foundations without any claim for damages or indemnity against Owner, or diminution or abatement of rent.

  • Heating, Ventilation and Air Conditioning Landlord shall furnish to the Premises heating, ventilation and air-conditioning (“HVAC”) in accordance with the Design Standards set forth in Exhibit D during Ordinary Business Hours. Landlord shall have access to all air-cooling, fan, ventilating and machine rooms and electrical closets and all other mechanical installations of Landlord (collectively, “Mechanical Installations”), and Tenant shall not construct partitions or other obstructions which may interfere with Landlord’s access thereto or the moving of Landlord’s equipment to and from the Mechanical Installations. No Tenant Party shall at any time enter the Mechanical Installations or tamper with, adjust, or otherwise affect such Mechanical Installations. Landlord shall not be responsible if the HVAC System fails to provide cooled or heated air, as the case may be, to the Premises in accordance with the Design Standards by reason of (i) any equipment installed by, for or on behalf of Tenant, which has an electrical load in excess of the average electrical load and human occupancy factors for the HVAC System as designed, or (ii) any rearrangement of partitioning or other Alterations made or performed by, for or on behalf of Tenant. Tenant shall install, if missing, blinds or shades on all windows, which blinds and shades shall be subject to Landlord’s approval, and shall keep operable windows in the Premises closed, and lower the blinds when necessary because of the sun’s position, whenever the HVAC System is in operation or as and when required by any Requirement. Tenant shall cooperate with Landlord and shall abide by the rules and regulations which Landlord may reasonably prescribe for the proper functioning and protection of the HVAC System. Tenant acknowledges that the server room in the Premises currently has three heat pumps installed, being two 4-ton units, and one 2.5-ton unit (the “Existing Heat Pumps”). The 2.5-ton unit is currently connected and operational. Tenant shall determine whether it is satisfied with the condition of the Existing Heat Pumps and Landlord shall not have any responsibility or liability for the condition, operation, maintenance, repair or replacement of the Existing Heat Pumps. Tenant may operate the Existing Heat Pumps. Tenant shall be responsible for, and pay directly for, all necessary maintenance and repairs to the Existing Heat Pumps.
