 - IEEE - 1188_2005 ¹öÀüÀÔ´Ï´Ù.
 
IEEE has updated its 1188- 2005 
 
 
2.4 The new IEEE standard 1188-2005
?
Now, IEEE has updated its 1188-1996 to 1188-2005 standards, the provisions of 5.2.2 is still time for each quarter testing battery / ohm single internal value.
?
Annex C of Article C.4 with the battery / ohm single-house testing related to new and increased 2.
?
(1) provides that in 1188-2005 "and the reference value compared to 30% of the value of the test-ohm to 50% of the change can be seen as a clear change" in 1188-1996 in the standard provisions of the "value of more than 20 ohm test % Change can be seen as a clear change. "  (1188-1996¿¡¼­´Â 20% °ªº¯È­¿¡ µû¶ó ÃàÀüÁö ¼¿ ±³È¯À» ±Ç°íÇÏ¿´À¸³ª 1188-2005¿¡¼­´Â 30%~50% º¯È­½Ã¿¡ ±³È¯À» ±Ç°íÇÏ¿´´Ù´Â ¼³¸íÀÓ.)
?
The new standards on the percentage had more detail, at the same time with the France Telecom, Brazil Telecom, British Telecom, as well as many major U.S. telecommunications carriers is consistent with the results of research, Midtronics and also the company's line of research results ( Midtronics instrument of default warning limit of 70% and 60% for the replacement of the limits);

(2) ohm value of the test are likely to have batteries in parallel, because each set of batteries in parallel so that the tester's test signals an increase in the current path, the impact of the battery pack inside the battery more than the number of cases Especially (for example, when a 48V battery from the 4 12V battery composed of the time).
?
This can affect the resistance of the parallel standard formula calculated to make it to quantify, but the most accurate and reliable method to exclude the impact of this is to make batteries and then off-line for testing. This new content and in front of France Telecom in 2001 INTELEC published articles found in the line.
?
3, the Government of India Ministry of Communications Communications Engineering Center on the standard VRLA new amendments
?
Jan 5, 2005, the Indian government revised the standard VRLA number: GR/BAT-01/03.MAR 2004, the specific changes are as follows: Since the resistance and conductivity test reading test compared to the more stable, it was decided for the sake of consistency, Conductance method will be used as the sole method of testing (No. 5.11.3 and section 7.6.3.10); 5.11.3 due to be the first to adopt the provisions conductive has been replaced by measuring impedance measurement, so that all the "resistance" in all in all "Conductivity". (Article 5.5 and Article 7.3.1)
?
Today, in India as well as the battery industry in the telecommunications industry are no longer of any use of resistance testing instruments, using all the conductivity of the battery tester to carry out maintenance. ([url = http://www.taiyanggonggong.com/jobs/index.asp ] Solar talent [/ url]
