34、 in ANSI C82.9 and C92.1. For additional definitions, see ANSI/IEEE 100. (1) Stiff 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 F
35、OR ELECTRICAL PERFORMANCE TESTS 4.1 Power supply. Except for the testing of ballasts 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 th
36、at the rms (root-mean-square) summation of the harmonic components will not exceed 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
37、 or other voltage transformation devices used in the circuits shall have a power 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 unde
38、r test shall be 25C 5C. 4.3 Lamp Position. The lamp position, both for the measurement 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 characteri
39、stics of lamps operating on reference ballasts have been established for vertical 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 outline
40、d in ANSI C78.389 should be followed carefully. 2005 American National Standard Lighting Group, in affiliation with NEMA Page 7 of 29 Copyright National Electrical Manufacturers Association Provided by IHS under license with NEMANot for ResaleNo reproduction or networking permitted without license f
41、rom IHS-,-,-ANSI C82.6-2005 4.4 Lamp Stabilization. 4.4.1. 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 stabilization method: Before any measurements are
42、taken, the lamp shall be operated within 3% of rated wattage in an ambient temperature of 25oC 5oC 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 minutes. It could be as much as 6 hours or more for a m
43、etal-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 test ballast during lamp stabilization, causing r
44、esistance 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 stabilized lamp to the test ballast without extinguishin
45、g 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-stabilization time is important and is typically
46、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 standby ballast should be adjusted to +/- 2% of t
47、he 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: Because 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
