Current transformers are used for electrical measuring instruments and / or electrical protective devices. They are very useful in high power circuits where the current is large. Current transformers are subdivided into two main categories. MEASURING CURRENT TRANSFORMER PROTECTIVE CURRENT TRANSFORMERS These transformers are used in measuring and indicating current, that is to reduce the line current to a value which is suitable for standard measuring instruments, relays etc. These transformers are used for over current and undercurrent relaying for power circuit protection. TYPE : Current Transformers are normally categorized as Ring / Bar type and Wound Primary Ring / Bar type current transformer :A current transformer where primary winding is provided by 'the user. Wound primary current transformer A current transformer having a primary winding of more than one full turn wound on core. Current Transformers are wound on Toroidal cores which virtually eliminates error due to leakage flux. Adjusting the number of secondary turns may compensate for some errors. Electrical Specifications : Type : Ring and wound type Type. : Tape insulated ring type and Epoxy resin potting type. Primary Current : 50 Amp. To 3000 Amp. in Ring type, 25 Amp. To 600 Amp. in epoxy resin Secondary Current : 5 Amp. and 1 Amp. for Ring type, 0.2 , 0.1 and 0.05 Amp. for epoxy resin ( other on request) Burden : 5, 10, 15 VA. for Ring type, 0.25, 0.5, 1 and 2 VA. for epoxy resin type ( other on request) Accuracy Class : 0.2, 0.5, 1.0, 5.0, 10.0 Frequency : 50 Hz Operating Temp. : - 10 deg. C to 40 deg. C. Conforms to : IS 2705
