When using this procedure, it should pay attention to using the currently valid version of the referenced standard.
3 metering performance requirements
3.1 basic error
When the ambient temperature is 0 ℃ ~ 40 ℃, relative humidity less than 80%, ambient electromagnetic interference and mechanical vibration can be ignored
Murillo, measuring voltage transformer rated frequency, rated power factor and load secondary rated secondary load
When any value between 25% to 100% of each accuracy level of error should not exceed the limits in Table 1.
The actual error curve voltage transformer should not exceed the scope of Table 1 lists a line formed by connecting the error limits.
