Product Parameter:
Electrical Performance Requirements
o Winding Requirements
o Primary : Lead out by copper Conductor
o Secondary: Lead out by UL1007 #24 Black and Red Wires.
o Insulation Strength Between turns.
o Keep the secondary coil open, then input 10A(rms) current to primary coil for one
minute, the insulation between turns of CT should be without any damage
o Insulation Resistance
o Insulation Resistance between primary and secondary winding should be greater
than 1000 MΩ
o Insulation strength
o The primary to secondary winding can undertake power frequency AC 4000V and
will not be penetrated for one minute by 1ma creepage
o Impulse Test
o The CT should with stand an Impulse voltage of 8KV, conducted under IEC Standards
o Magnetic Influence Test
o The Accuracy of the CT should be within 1% in the presence of 0.7T magnet at a
distance of 30mm with base current flowing through the primary winding at unity
2power factor.
o Short time over Current Test
o The accuracy of the CT should not be changed by an over current of 3000A RMS
applied for half cycle at 50Hz.
