ANSI C82.2-2002 (R2007, R2016) Page i 2016 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by The American National Standards Institute, Inc. (

13、ANSI) that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the AN

14、SI Board of Standards Review, substantial agreement has been reached by directly, 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 effor

15、t be made toward their resolution. The existence of an American National Standard does not in any respect preclude anyone, whether s/he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. It is inte

16、nded as a guide to aid the manufacturer, the consumer, and the general public. The American National Standards Institute, Inc., does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to i

17、ssue an interpretation of an American National Standard in the name of the American National Standards Institute, Inc. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on this title page. CAUTION NOTICE: This American National Standard may be revised

37、er their rated line voltage or for certain types of tests at other voltages as specified in ANSI C82.1. In addition, specific test input voltages as related to tests conducted on ballast-lamp combinations can be found in the appropriate lamp data sheets. Where ballasts are labeled for a range of pri

38、mary voltages, testing should be conducted on the lowest and highest USA design center voltage for the given ballast. Ballasts shall always be operated at their rated frequency. 4.2 Line Voltage Wave Shape Throughout the full range of test requirements the AC voltage supply at the input terminals to

39、 the ballast-lamp combination shall have a wave shape such that the RMS summation of the harmonic components does not exceed 3% of the fundamental. 4.3 Stability of Supply Voltage The line voltage shall be as steady and free from sudden changes as possible. For best results the voltage should be reg

40、ulated to within 0.1%. If adequate automatic regulation is not available, constant checking and readjustments are essential for obtaining accurate measurements.14.4 Supply-Source Impedance The supply source shall have sufficient power capacity and sufficiently low impedance, compared with the ballas

41、t impedance, to ensure that the voltage to the ballast or lamp-ballast combination does not vary by more than 3% with the lamp-ballast combination in and out of the circuit. 1 If the static type voltage stabilizer is used, it is particularly important to check the wave shape to see that it meets the

42、 specification given in 4.2. This should be checked both with and without load. ANSI C82.2-2002 (R2007, R2016) Page 3 2016 National Electrical Manufacturers Association 5 Electrical Supply CharacteristicsReference Ballast Measurement Circuits The general characteristics of reference ballasts are des

43、cribed in ANSI C82.3 and ANSI C78.375. The specific values of impedance, reference current, and rated input voltage for the reference ballasts corresponding to each lamp type are given in the appropriate lamp data sheets. The reference ballast while operating fluorescent lamps shall meet all electri

44、cal supply characteristics cited in ANSI C82.3 and ANSI C78.375. 6 Ambient Conditions for Lamp Measurements Variations in ambient temperature, air movement along the bulb wall surface, and lamp burning positions can affect the electrical characteristics as well as the output of a reference lamp. The

45、 ambient conditions for lamp measurements cited in ANSI C78.375 shall be followed when testing line frequency ballasts on reference lamps. Unless otherwise specified, the ambient temperature for all tests is 25OC 1OC. 7 Test Measurement Circuits 7.1 Circuit Grounding In all of the wiring diagrams sh

46、own in the standard, the side containing the instruments current coil is shown connected to the grounded supply conductor. This is a recommended safety precaution, since many types of portable instruments have current coil terminals that are not insulated and that can constitute a shock hazard if no

47、t kept at ground potential. In those situations where the available power source is grounded at some other potential (for example, a 120/240, three-wire supply with a midpoint ground), the grounded connection as shown in these diagrams shall not be used, but in such cases other arrangements shall th

48、en be made to minimize the shock hazard. ANSI C82.2-2002 (R2007, R2016) Page 4 2016 National Electrical Manufacturers Association 7.2 Basic Instrument Circuit The recommended methods of connecting the instruments to the lamp and ballast circuit are provided in and Figure 2. If individual instruments

49、 are used then only one instrument at a time shall be connected in the measurement circuits.
