7.Typical Application and Parameters:
The parameters are listed in the following table while the application is shown as the figure.
Model | Rated Input Current | Rated Output Current | Rated Sampling Resistance RL | Rated Sampling Voltage | Rated Sampling Voltage | Non Linearity | Linear Range | Withstand Voltage |
TA1320A-1M | 50A | 100mA | 12.5Ω | 1.25V | ≤30’ | ≤0.2% | 2 times of the rated value | ≥6KV |
TA1320A-2M | 50A | 50mA | 50Ω | 2.5V | ≤20’ | ≤0.2% | ||
TA1320A-3M | 50A | 25mA | 200Ω | 5.0V | ≤15’ | ≤0.2% |
● Notes:
a.In practical applications, the sampling resistor should be smaller than or equal to the rated value given in table above in order to improve the non-linearity and phase shift.
b.We can have it customer-made if required current changing ratio is not listed in the table above.
8.Attention:
① Connect the primary winding of the current transformer in series with the measured current loop, and operate the secondary winding in near short-circuit mode.
② Do not allow the secondary winding of the current transformer to be open-circuited and do not install any fuse in the secondary circuit.
