Current transformer provide a simple, inexpensive and yet accurate means of sensing current flow in power conductors. They are available in 5 basic configurations:
1.1,Three phase and single phase energy meter CT's are available from measuring currents 0-120Amps.
1.2,PCB mount (H-CT003 series) Core CT's are available for measuring currents from 0 to 150 Amps.
1.3, Ring/ZERO(H-CT004 series) Core CT's are available for measuring currents from 0 to 5000 Amps.
1.4, Clamp on Core CT's(H-CT007 series) are available for measuring currents from 0 to 5000Amps.
1.5,BH (H-CT021 series) Core CT's are available for measuring currents from 0 to 6000 Amps.
2,About Manganin shunt.
Manganin shunt provide an accurate DC millivolt signal to drive ammeter indicators, overload protection and control devices, expecially for higher AMP. The shunts supply voltage drop proportional to DC current which is measured and indicated by moving coil meter with dial calibrated in AMPS
