Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly

8、 and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The existence of an American National Standard

29、ff Line: A stiff line is defined as a sine wave source that exhibits voltage regulation (change of rms voltage from no load to full load divided by rms voltage at full load) of no more than 0.5%. 4.0 GENERAL CONDITIONS FOR ELECTRICAL PERFORMANCE TESTS 4.1 Power supply. Except for the testing of ball

30、asts designed for use on constant- current supply circuits, the AC voltage supply at the input terminals to the ballast-and-lamp combination shall, throughout the full range of test requirements, have a wave shape such that the rms (root-mean-square) summation of the harmonic components will not exc

31、eed 3% of the fundamental component. The impedance of the power source, as measured at the point where the ballast-and-lamp combination is connected, shall not exceed 3% of the ballast impedance. Variable autotransformers or other voltage transformation devices used in the circuits shall have a powe

32、r rating at least five times the wattage of the lamp intended to be operated on the ballast under test. 4.2 Ballast Conditions. For normal operational tests, the ambient temperature and the temperature of the ballast under test shall be 25 C 5 C. 4.3 Lamp Position. The lamp position, both for the me

33、asurement in the reference- ballast circuit and for the measurement of the commercial ballast being tested, shall be vertical base up unless otherwise designated by the lamp or commercial ballast manufacturer. The characteristics of lamps operating on reference ballasts have been established for ver

34、tical and or horizontal operation, the lamp positions most commonly used in ballast measurement work. When a lamp is operated in other than a vertical position the measurement becomes more complicated, and the method outlined in ANSI C78.389 should be followed carefully. 2005 American National Stand

Lamp pre condition: The lamps used for ballast measurements shall, unless otherwise specified, have been seasoned a minimum of 100 hours prior to their use in the ballast tests. 4.4.2. Basic stab

36、ilization method: Before any measurements are taken, the lamp shall be operated within 3% of rated wattage in an ambient temperature of 25 o C 5 o C until the electrical parameters of the lamp cease to change. The lamp burning time required to achieve this lamp stabilization is a minimum of 30 minut

37、es. It could be as much as 6 hours or more for a metal-halide lamp if the lamp is moved while it is still hot or if its orientation is changed. After the stabilization process has begun, the lamp shall not be moved or repositioned until after the testing is complete. In order to avoid heating up the

38、 test ballast during lamp stabilization, causing resistance changes and therefore resulting in unrepeatable data, it is necessary to warm up the lamp on a standby ballast. This standby ballast should be a commercial ballast of a type similar to the test ballast in order to be able to switch a stabil

39、ized lamp to the test ballast without extinguishing the lamp. A fast-acting switch is recommended; however, a make-before-break switch may be required on a high-pressure-sodium lamp to prevent it from extinguishing during switchover. Once the lamp has been transferred to the test ballast circuit, re

40、-stabilization time is important and is typically 1 minute for mercury and high-pressure-sodium lamps and 3 minutes for metal-halide lamps. To avoid test ballast heat-up, measurements should be taken within 5 minutes after re-stabilization. If a HPS lamp ballast is under test the lamp wattage with a

41、 standby ballast should be adjusted to +/- 2% of the nominal lamp wattage, (see ANSI C78.42) if the ballast does not have a fixed power output design. (Informative Note: The effect of heat on ballast operation is under consideration by the ad hoc group.) 4.4.3. Alternative Stabilization method: Beca

42、use in some cases, such as low frequency electronic ballasts, the transfer from the reference ballast to the ballast under test is undefined, the following alternative method should be followed to ensure testing result reproducibility: 4.4.3.1. The lamp characteristics should be determined with a re

43、ference ballast and recorded for future comparison. 4.4.3.2. The same lamp will be driven by the ballast under test for 15 minutes. 4.4.3.3. The electrical measurements should be taken within 2 minutes after the 15- minute stabilization period. 2005 American National Standard Lighting Group, in affi

44、liation with NEMA Page 8 of 29 ANSI C82.6-2005 4.5 Instrumentation CAUTION: Certain instruments connected in parallel with the lamp may be damaged or destroyed when subjected to the starting pulse of ballasts that supply such pulses (such as those for high-pressure sodium and metal-halide pulse-star

45、t lamps). It is recommended that such instruments be connected after the lamp is started and that some arrangement be provided to remove the lamp ignitor from the circuit or otherwise prevent the ignitor from unexpectedly operating. (Note: digital instruments, that meet the requirements described in

46、 this standard, are preferred to analog instruments). 4.5.1 Accuracy. It is desirable that instruments be chosen so that the indications to be read will be in the upper third of the range. Instruments should be selected which have a guaranteed accuracy commensurate with the requirements of the test

47、and shall not have an accuracy less than the following: 4.5.1.1 Analog Instruments: Ammeters and voltmeters: 0.5% up to 800 Hertz Wattmeters: % up to 1000 Hertz for power factors of 50% to 100%; 0.5% up to 125 hertz for low-power-factor (0% to 20%) circuits. 4.5.1.2 Digital Instruments: Accuracy (X

48、percentage of the reading + Y percentage of the scale per instrument manufacturer specification.) DIGITAL INSTRUMENTATION REQUIREMENTS Equipment Digits Resolution Basic Accuracy a.c+d.c. True RMS 2kHz. Voltmeter 3 0.50% yes Ammeter 3 0.50% yes Wattmeter 3 0.50% yes 4.5.2 Impedance Limitations.
