JB/T 5472-1991 Instrument current transformer GB/T 16927.1-1997 high voltage test techniques Part 1. General test requirements When using this procedure, it should pay attention to using the currently valid version of the documents cited.3 metering performance requirements3.1 basic error Ambient temperature 0 ℃ ~ 40 ℃, relative humidity less than 80%, ambient electromagnetic interference and mechanical vibration can be ignored, Measuring current transformer rated frequency, rated power factor and load secondary rated secondary load of 25% to 100% When any value between each level of accuracy of error should not exceed the limits in Table 1. To meet the special requirements of the system Made S-class current transformers, each accuracy level of error should not exceed the limits in Table 2. The actual error curve of the current transformer, a line should not exceed Table 1 or Table 2 error limits listed in connection formed range.
