一种新型的交流大电流测量标准装置
A Fire-New Standard Measurement Device of Heavy AC Current
摘要
Abstract
On the principle of current comparator, a fire-new standard measurement device of heavy AC is developed that can be used for on-site test and calibration of the output CT of ac generators. Testing of the comparator indicates that its accuracy is better than 0.04 %, including the error of ratio and phase angle. The error in repeatability of openable-core is 0.007 %. The ability of resistance to external magnetic field isgreater than 0.01 T.关键词
