Thursday, August 14, 2008. Decimal or Base Ten or Denary Numeral System. Decimal is a base (or radix) 10 numeral system. Meaning, the system has ten symbols or numerals to represent any quantity. These symbols are called Digits. The Hindu-Arabic numeric system and Chinese counting rods system are the two systems that required no more than ten symbols. Decimal numeral system is the most commonly used numeral system perhaps because humans have ten digits over both hands. So 17591 can be expanded as 1x10.

http://transformertechnology.blogspot.com/2009/06/transformer-testing-at-site.html
The way to explore the Technologies using in Transformer. Welcomes you to world of Electrical Transformers. Monday, June 15, 2009. TRANSFORMER TESTING AT SITE. Everyone knows before commissioning or charging any equipment it must be need to test before putin to service, like that the new transformer is also need to ensure everything is fine. So, some tests are required to confirm. those are all called Pre-commissioning tests.some important tests are mentioned here for easy ref,. Ii) Turns / voltage Ratio.

Transformer Technology (TRANSTECH): Transformer Efficiency
http://transformertechnology.blogspot.com/2009/07/transformer-efficiency.html
The way to explore the Technologies using in Transformer. Welcomes you to world of Electrical Transformers. Friday, July 10, 2009. Efficiency = Output / Input. Input - Losses) / Input. 1- (Losses / Input) ; input = VI cos θ ; (say, losses/ VI = x). Efficiency = 1 - (x/ (cos θ x). 1 - ( x/cos θ)/(1 x/cos θ). Efficiency = (VA * cos θ) / ( VA * cos θ) Losses) * 100. Transformer KVA = 1000 KVA; 11 KV/ 433 V, Full loadLosses measured = 12.5 KW. Calculate efficiency in full load at .8 PF, .9 PF and UPF.

http://transformertechnology.blogspot.com/2009/06/magnetic-balace-test.html
The way to explore the Technologies using in Transformer. Welcomes you to world of Electrical Transformers. Monday, June 15, 2009. Magnetic Balance test used to find the distribution of Flux (Magnetic), Core Assembly Condition and defect in winding (If any). It may check at HV Side or LV Side as per requirement/ site condition. For Delta connections, apply voltage must be in Phase - Phase like U and V, V and W and W and U. U and N = (V and N) (W and N); 240 = 198 42. Magnetic Balance at HV side.
