(ANSI) that the requirements for due process, consensus, and other criteria for

15、 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 ANSI Board of Standards Review, substantial agreement has been reached by direct

16、ly, 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 Stand

27、ibes the essential design features and operating characteristics of reference ballasts for fluorescent lamps. The items specified are those that have been found necessary to ensure accurate and reproducible results when either lamps or ballasts are being tested. It includes requirements for both lin

28、e frequency and high-frequency circuits. The specific values of rated input voltage and impedance for each size of lamp are listed in the applicable ANSI C78 lamp standard. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions

ANSI C82.3-2016 Page 2 2016 National Electrical Manufacturers Association 5 Design characteristics 5.1 General design for line frequency reference ballasts A l

35、ine frequency reference ballast is a self-inductive coil, with or without an additional series resistor for power factor adjustment, designed to give the operating characteristics of Clause 6. It may be used either in a circuit employing a starter or, where applicable, in a circuit including separat

36、e power sources to heat the lamp cathodes. Further details of those circuits are given in ANSI C78.375. 5.2 General design for high-frequency reference ballasts at 25 kHz A high-frequency reference ballast is a resistor or choke-coil designed to give the operating characteristics of Clause 7. 5.3 Pe

37、rmanence of impedance 5.3.1 Fixed-impedance type ballasts Since this type of reference ballast is intended to serve as a permanent baseline of reference, it is vitally important that the ballast is constructed as to provide permanence of impedance under normal conditions of use and abuse. A recheck

38、of the impedance of the ballast shall give values within 0.1% of those previously determined. 5.3.2 Adjustable-impedance type ballasts. This type of reference ballast, when adjusted to any given value of impedance, shall be capable of holding that adjustment through normal periods of use. For this p

39、urpose, suitable means shall be provided for mechanically locking the movable core (or other movable parts) in any desired position. 5.4 Enclosure A reference ballast shall be enclosed for mechanical protection. In the case of the adjustable-impedance-type ballast, the series resistor need not be in

40、 the same enclosure with the reactor. Care should be taken for proper conduction of the dissipated wattage losses. 5.5 Magnetic shielding (for 60 Hz reference ballast) A reference ballast should be protected against magnetic influence in such a way that its impedance at reference current shall not b

41、e changed by more than 0.2% when a half-inch (13-mm) plate of magnetic steel is placed within 1 inch (25 mm) of any face of the ballast enclosure. The steel plate shall have dimensions at least 2 inches (51 mm) greater than the maximum dimension of the ballast enclosure and shall be placed in geomet

42、ric symmetry to each surface as tested. In the event that a reference ballast is not magnetically shielded, precautions shall be taken to keep magnetic objects far enough removed from the leakage field so that the impedance of the ballast will not be altered by more than the 0.2% mentioned above. 5.

43、6 Inclusion of instrument current coils When an adjustable-impedance type reference ballast is being used, a choice may be made as to whether the impedances of the instrument current coils (the ammeter and wattmeter) will or will not be included as part of the impedance of the reference ballast. Eit

44、her procedure is satisfactory, however if the coils are included in the original calibration they must be left in the circuit at all times during subsequent use. Figure 1 shows the current coils included. ANSI C82.3-2016 Page 3 2016 National Electrical Manufacturers Association Current terminals of

45、instruments are shown as: Potential terminals of instruments are shown as: Figure 1 Circuit for impedance and power factor measurement 6 Operating characteristics for 60 Hz 6.1 Rated supply voltage and frequency The rated supply voltage and frequency of a reference ballast shall be in accordance wit

46、h the value given on the relevant lamp data sheet in either ANSI C78.81 or ASI C78.901. 6.2 Impedance The ratio of voltage to current of a reference ballast shall have the value given on the relevant lamp data sheet in either ANSI C78.81 or ANSI C78.901, subject to the following tolerances: a) 0.5%

47、at the calibration current value; b) 3% at any other value of current from 50% to 115% of the calibration current. See figure 1. 6.3 Ballast power factor The effective power factor of the reference ballast (ratio of wattage loss to the product of ballast voltage and current) when the ballast is carr

48、ying reference current shall be 0.075 0.005 unless specified otherwise on the individual lamp data sheet. See Figure 1. 6.4 Temperature rise When the reference ballast is operated in an ambient air temperature of 25C and at calibration current and rated frequency, and after thermal stabilization, th

49、e temperature rise of the ballast winding shall not exceed 25K, when measured by the change in resistance method.
