A1.5 Current transducers (CT or TA)
ThearmaturecurrentofthemotorismeasuredbytwoACcurrenttransducersinsertedonthelinesideofthe
powerbridge;see,forexample,("Figure9.4.4:ESE5771TPD32-EV-CU-230...690-THY1-XX_1"onpage425).
Transducerswithdifferentprimary/secondarycurrentratiosareavailableonthemarketandcanbeusedwith
theCU.TheTPD32-..seriesusesaCTwithstandardcurrentvaluesof0.4Aor0.5Aonthesecondarywinding.
Werecommendtheuseofcurrenttransducerswithasecondarycurrentofnotmorethan1A.
Someofthecurrenttransducersavailableuponrequestarelistedbelowwiththerelativetechnicaldata:
