What is the operating frequency of a precision current transformer?

For example, LCTA21, such as LCTA21CE operating frequency is 20Hz-20KHz, does this range refer to the frequency range of the signal under test? If it is a refrigerator or other load, if there is interference in the 50Hz power frequency, such as a 100KHz burst interference signal, can this signal be detected by the transformer?

 


Refers to the frequency range over which the device can operate correctly. 50Hz belongs to this range and can be measured correctly. 100kHz is out of range. It may be measured, maybe not, at least not accurate.
