Split-core current transformers (CT’s) from Enetics are available in three conductor diameter ranges and cover a wide span of operational current flow. Superior grain-oriented silicon steel and symmetrical uniform coil design and construction techniques deliver high linearity and a broad frequency response for both 50 and 60 Hz applications. Low phase shift error contributes to accurate kWh measurements.
These CTs require no external power and provide full scale output voltages of either 330 mV rms or 1.0 Vrms. Designed with an internally burdened secondary that eliminates the presence of high voltages during open circuit secondary conditions, these CT’s provide a welcomed level of reduced shock hazard for field personnel. All CT’s are UL, CSA, and CE certified.
Three body sizes are available ranging from 0.75 inch to 3 inch apertures to accommodate multiple conductor diameters. Standard lead length is 10 feet, additional lengths available by request. Operational current ranges should be selected to match the maximum anticipated current levels. Split-core CT’s are not recommended for outdoor applications. Enetics flexible Rogowski CT’s are recommended for outdoor installations.
