Power calculation obviously depends on the precision of the accuracy of the current transformer

Power monitoring system should be based on careful selection of very specific characteristics required current transformer:
1 Accuracy - In most applications, the measurement accuracy of the efficiency of the entire system has a direct impact. Power calculation obviously depends on the precision of the accuracy of the current transformer. A power meter may require accuracy  Circuit breaker  1% of the current transformer, and the accuracy will normally expensive materials and  mcb circuit breaker  processes related. An alternative is the application of each of the transformer of the power meter is calibrated. Taking into account the specific characteristics of each transformer, allows the power meter set at its most precise mode of operation and the variable transmitted from one transformer to another transformer. Learn linearity, drift and repeatability as well as its overall inaccurate readings to compensate opens the door to all kinds of new technology.
