Claim:
1. A power device having a current transformer, the power device comprising: first to Nth current transformers; an integrated measurement panel connected to the first to Nth transformers and comprising a memory configured to store compensation values for compensating abnormal linearity characteristics for each current interval of one or more current transformers of the first to Nth current transformers, wherein the integrated measurement panel is configured to: measure current values of locations where the first to Nth transformers are installed using current values detected by the first to Nth transformers; determine if compensation of each of the measured current values of the first to Nth current transformers is necessary; and compensate one or more of the measured current values using the compensation values stored in the memory when compensation is necessary for the one or more of the measured current values.
