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 systemSuitable for electrical fire monitoring
systemsFlexible output methodThrough structure ,epoxy resin
casting,good stabilityHigh permeability permalloy or
nanocrystalline ,with good linearity and high sensitivityExcellent
balance characteristics and extremely strong immunity to
electromagnetic fields . Recommend
