摘要：
The use of cryogenic current comparators at NPL has been limited so far to currents of 100 mA. A new current comparator with a maximum current capacity of 100 A has been developed and will form the basis of a resistance ratio bridge for low value resistors with a relative uncertainty of 10(-7) or better.
