Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.
