Abstract :
The problem of obtaining an accurate representation of 330-kv bus potential to be used in metering energy and reactive interchange over 330-kv tie lines was economically solved by the use of a network applied to a power transformer to compensate for voltage transformation errors due to load on the transformer. This paper describes the design, testing, and operation of such a potential compensating network used with a power transformer. By its use the need for two 3-phase banks of expensive 330-kv potential transformers together with their foundations and switches was eliminated at no sacrifice of metering accuracy.
