The measurement of the transport critical current of T1-1212 superconductor tapes at three different annealing temperature and time were completed and recorded using the 1uV/cm criteria. The superconductor tapes labeled asM1, M10 and M11 were annealed at temperature of 890C for 30 minutes, 800C for 30 minutes and 800C for 1 hour respectively. The readings for the V-1 characteristics were obtained through the implementation of the standard four-point probe attached to the superconductor tapes and immersed in the boiling temperature of liquid nitrogen. The values of the V-1 characteristics were converted to uV/cm values by dividing the voltage values with the length of two voltage probes. From 1uV/cm criteria for the three tapes, we found that M10 has the highest value of critical current, I and no critical current was obtained sample M1.
