14、 of federal and military specifications and standards are available from the Naval Publications and Forms Center, (ATTN: NPODS), 5801 Tabor Avenue, Philadelphia, PA 19120-5099.) 2.2 Order of precedence, In the event of a conflict between the text: of this document and the references cited herein, th
15、e text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Qualification. The monitors furnished under this specification shall be products which are qualified for listing
16、on the applicable qualified products list at time set for opening of bids (see 4.4 and 6.6). 3.2 General requirements. The monitors shall be in accordance with the requirements of MIL-E-917, and the requirements of this specification except as otherwise specified in the contract or order. 3.2.1 Pain
17、ting. Parts not fabricated of a corrosion-resisting material or having a corrosion-resistant treatment as specified in MIL-E-917 except for semi- conductors, shall be painted as specified in MIL-E-917. Only one coat of gray enamel shall be applied on the outside of the enclosure. Touching-up will be
18、 permitted for marks or scratches due to factory handling. Cadmium plating spec- ified in MIL-E-917 shall not be used. 3.3 Performance. 3.3.1 Alternating current (ac) monitors. The ac monitor, when connected similarly to that shown on figure 1 to a 3-phase ac generator with any leading or lagging po
19、wer factor (pf) condition, shall perform the functions specified herein. The power characteristics are as specified in MIL-STD-1399, section 300. Each monitor shall receive a 3-phase, 115 volt supply from the generator side of the generator circuit breaker via open delta connected potential transfor
20、mers. The monitor current sensing supply shall be obtained from two current transformers with a rated 5 ampere secondary current. One current transformer is located in phase A, and the other in phase C. The monitor shall not be damaged by voltages from O through 160 volts, currents to 10 amperes, an
21、d by frequencies from O through 63 Hz during the time the generators are coming up to rated speed. 3.3.1.1 Trip pickup, reverse power monitors. The performance of the monitor shall not be adversely affected under reverse power conditions by a generator load unbalance up to 50 percent at 0.4 lagging
22、to unity pf and a phase voltage unbal- ance up to 5 percent. Under any combinations of unbalance, on any phase up to these limits, the monitor shall provide tripping action at a preset reverse power level of 2.5 to 10 percent of rated load reverse power at unity pf (see 3-3.4). The trip point shall
23、be continuously adjustable over this range. The monitor shall not trip under any condition of forward 3-phase pawer, with load unbalance up to 100 percent and pf from 0.4 to unity, leading or lagging. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,
24、-3.3,1.2 Trip pickup, power-sensinv monitors.
