750kv current transformer Calibration

SummaryPurposeOperationTypesApplicationsVariationsExampleMechanismSafetyAvailabilityIntroductionConstructionAdvantagesThe Current Transformer ( C.T. ), is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary. Current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a standard ammeter.
