The TR21 series Residual (zero sequence) current transformer are designed to acquire residual (zero sequence) current signal .residual (zero sequence) current usually of the mA level and must be wound through the core ,which has a high requirement for balancing characteristics ,immunity to interference and linearity .
This series products has a wide measure range ,rated primary current transformer :10mA~5A ,rated secondary current range :0~5mA,excellent high permeability magnetic core and advanced producing process flow,ensuring its accuracy range ,reliability ,etc.
Suitable for motor protection ,relay protection,small current grounding system
Suitable for electrical fire monitoring systems
Flexible output method
Through structure ,epoxy resin casting,good stability
High permeability permalloy or nanocrystalline ,with good linearity and high sensitivity
Excellent balance characteristics and extremely strong immunity to electromagnetic fields .
