New digital electronic transformer

With the development of the power system, the traditional electromagnetic transformer has been unable to satisfy practical needs. New digital electronic transformer due to the introduction of optical fiber transmission, the new signal processing unit and a digital  electric meter , with insulation structure is simple and reliable, small size, high accuracy, and other equipment interface is compatible with other significant advantages, which gradually gained wide acceptance and  circuit breakers  . Paper, based on the principle of electromagnetic induction coil electronic  Electric transformer  (ECT) and the partial implementation of the design method to analyze the combined unit and laser for energy and other major part of the implementation plan. Type test results show that the prototype. The system is fully up 0.2 accuracy metrics and comply with the latest standards IEC61850 requirements.
